Okay, let's just dissect this a bit shall we.
Do his quotes get taken out of context? Maybe a little bit, but if you take a look at the top of the page, you are on the leading Manchester United forum. It is perhaps expected that a bit of spin is put on the words of Liverpool's manager for comedic effect by Manchester United fans on a Manchester United forum. However, I don't there's much you can do with context when your manager is talking about Ashley Young making a tackle against a team that was not Liverpool, and before your biggest game of the season, against a team that is not Manchester United.
Are we obsessed with Jurgen Klopp? Not really sure. There's always a level of interest in the Liverpool manager because most United fans see Liverpool as their biggest rivals, regardless of what City are doing. However, when United fans are discussing Klopp as a result of Klopp talking about Manchester United, it's probably not that weird that Manchester United fans are talking about said comments on a Manchester United forum.
Oppo fans are welcome here. They're welcome to come here and discuss a great deal of things. However, issues can arise on this, a Manchester United forum, when they act as appointed guardians of their particular chosen team, calling out Manchester United fans for reacting to comments about Manchester United. There is a stark difference between you arguing with United fans who think, for example, that Klopp is a fraud and a perennial underachiever, and you arguing with United fans who are having a laugh at Klopp once again talking about United in a press conference when the match doesn't involve United.
If Manchester United fans are being negative about Manchester United on a Manchester United forum, they are doing so out of frustration and a desire to see improvements in the team that they support. If oppo fans are being negative about Manchester United on a Manchester United forum then they're more than likely doing it to take the piss or rub salt in the wounds after a recent result. I have seen plenty of insightful opinions, both negative and positive about Manchester United from oppo fans, even Liverpool fans, that have resulted in excellent discussion. Perhaps your comments weren't as insightful as you thought, or perhaps you posted them at a bad time. I'd say immediately following a loss is probably a bad time.
As for the last bit, and I'm not sure if you've noticed, but this is a Manchester United forum. I'm not sure what you expected, when you, a Liverpool fan, signed up for a Manchester United forum, so unless it's an actual serious discussion, I would perhaps wonder a bit more if you should bother responding to what is more than likely a hugely biased piss take. You've even said there that this is "something minor" so maybe you could all act a little less precious when Manchester United fans on a Manchester United forum have a bit of a laugh and find something to yap about when the manager of Manchester United's biggest rivals makes a comment about Manchester United.
Manchester United.
