You clearly knew that it was largely held view by EPL fans, your uber alles comment proves that. Of course people are free to respond to any part of a post that they want to.
Your initial response never answered me, you just went on to compare the leagues, which is fine you're entitled to do so, that's your prerogative if you so wish.
If you think there is no further discussion that is also fine, don't discuss it then. But making a sweeping statement that there is no discussion to be made is very arrogant and dismissive of other people who might want to discuss it further.
I was looking for a more in depth discussion on the topic as to why. You seem intent on flexing intellectual superiority, acting as if you are the lone authority on what merits discussion.
Okay, let's discuss further.
Who likes Liverpool?
Liverpool fans and overseas people who don't give a flying fuck about English football but hold them in high regard. Except Juventus.
Who likes Man United? Man Utd fans. Just them.
Who likes Chelsea? Chelsea fans. And people who liked a few of their teams because they were cute (late 90s) or because they were relevant and broke the Arsenal-Man Utd duo in England, or because of Mourinho or whatever other reason.
Who likes Manchester City? Mostly no one in particular outside of their own fans, with the latest (10 years) exception being those who have a strong dislike for Man Utd.
Who hates Liverpool? Everyone in England who does not support Liverpool. And fans of their rivals from everywhere else.
Who hates Chelsea? Tottenham fans. And some Arsenal fans more recently (~15 years).
Who hates Manchester City? Man United fans within England mostly. Most overseas Man United fans never really cared about this team until the last 10 years and in reality, they're not even as fierce a rival for the average foreigner Joe than Wenger's Arsenal was. The reason is because Man United's fortunes started to turn away after a couple of years within this rivalry and they never witnessed them as a competitive rival.
Who hates Man United? Everyone in the world who doesn't support Man Utd.
Now if you think I'm being arrogant when you, a declared Liverpool fan, suggests that it doesn't make sense that there's a negative reaction to Liverpool winning as opposed to Man City or Chelsea or even freaking Leicester winning if I may add, is sacrilege to your own football club. These guys are nobodies. In fact, you should be proud that people are dissing you now. You are defending European champions and have completely ridiculed domestic competiion, that's everything you need to know and say.
So I'm sorry but this is the fanbase of a club that chants "fuck off Chelsea FC you ain't got no history" or that doesn't even care that Man City is part of Manchester, a very historic and important cross-town rivalry in England and they've only viewed Man Utd as their main rivals. Which is quite weird since between almost 40 championships won they barely competed for one with eachother like 3 times.
Also, since your next question might be why was the PL considered so great by the same people when Man Utd was winning, it's exactly because as I say all the time, Man Utd is mostly a marketing company (and a corporation that created "modern football" since Glazer took over, with Arsenal following suit). Man Utd must be the biggest and best football brand in the world so we have to claim that they play in the best league in the world. Not sure how old you are or when you started paying attention, but Man Utd being "the most popular team" and the PL being "the most important/entertaining/amazing or greatest or best league in the world" has been going on since 1997 when the then overweight Eric Cantona who had given up on competitive football decided to retire officially and they run out of selling points. It was also part of the centenary anniversary of top flight football in England, so it just took off from there and Man Utd took complete advantage of this and made themselves more relevant than they should have been considered due to recent domestic success. And that Treble obviously took things to the next level. It's like today, where as you say they claim to be the best season ever in Europe and what not. They do have a claim, and that's what makes them even more annoying. We'll be hearing about that 2019-20 season for decades to come unless it starts becoming a trend which will a) vindicate them and b) make them even more annoying.
It's like England NT. They suck, everyone knows it, even in 2018 it was obvious that they weren't really that good, but with some luck and good draws, they managed to carry on until the semi finals. And now we'll be hearing about how they are Euro 2020 favorites and World Cup 2022 favorites. Same way World Cup 1990 made them Euro92 favorites (didn't win a game) or World Cup 1994 (didn't even qualify). Then Euro96, they host, reach the semis and ever since we've been hearing about how they're going to win the next one until like 2012 when they realized that they suck. So now 2018 reignited this and we'll be hearing it for years. This is what they do. England NT and Man Utd are pretty much getting the same treatment. Three options: A) You're a fan and you think that this is the best and most important team in the world, B) You're not really a fan but you like football in that neighborhood (ie PL for Man Utd reference and British for England NT reference) and you also claim that they are great despite not supporting them [unless you support a direct rival, see option C] and C) you just hate their guts and find them overrated.
But I say it once more, if you want to discuss PL quality with those guys, assuming you can ignore the Liverpool dominance pretext just ask them if Liga, Serie A, Bundesliga or Ligue 1 are better than PL. They won't say that the PL isn't the best league. They will still say the same shit. But they will dismiss Liverpool at every chance they get. It's not a rational state of mind. No one with a rational state of mind can claim that the PL has ever been the greatest league as there are way too many counterarguments that suggest it is not.
P.S: The only other English club that'd get the same treatement you feel you are receiving now would be Leeds United. Because, as the English say "we all 'ate Leeds 'cum". To the extent that it actually happened in the 70s when the claim was that when Don Revie left Leeds and they became irrelevant, English football dominated Europe whilst the English NT that he took over had turned to shit
