Exactly so. A lot of the time what passes for "discussion" is simply a series of attempts - often from the same small band of posters - to launch attack after attack. And when one attack fails - as they mostly all do, being based on nonsense - the grounds of the attack are shifted so that another angle of attack can be opened up.
If you're a Spurs fan, you can't say that Spurs have a good chance of top 4 without that being translated by some into a claim that Spurs are the best team in Europe. You're not allowed to say that we have a world-class training centre, without that being translated by some into a claim that Spurs are the best team in the world. I spend half my time responding to things that I haven't ever said, but which are presented as if they were fact.
In my view a lot of it stems from the insecurity of some United (and other) fans on here, who, despite what they claim, don't actually like to see continuing threats to their cosy notion of an "elite top 4" that's more or less fixed in place ... despite this notion having been blown out of the water already anyhow. What they want to see instead is big money being spent on "big players" by "big managers" at "elite clubs" who will then proceed to battle with each other, albeit using cheque-books instead of swords, in the Prem and CL gladiatorial arena, while all the other clubs - the "non-elite" - look on in supposed admiration.
So when Spurs come along and starting pushing United down the league and out into the EL, the attacking mission of this minority of gang-boy posters get fuelled up: show that Spurs are rubbish no-hopers, and use every piece of nonsense, thrown from every angle, to try and achieve this.
