I personally would never go on to a Federer forum and blather on about Andy while being condescending about Federer to his fans.
I'm sure I would be shown the door anyway if I was trashy enough to behave in such a manner.
Exactly! WTFs it all about? It's needle and wind up all the time, done in this so subtle "what have I done" way. It's called passive-aggressive behaviour.
If said person really wanted to discuss tennis in a dispassionate way, there are hundreds of neutral sites where fans of different players post.
Coming onto MW is for one reason only, to annoy.
And people are right, it is beginning to detract from this site.
