Again you'd be making an exception. Your desire is for anything related to his football or performances to be censured. That's why you don't want both separate performance and general thread for him and I'm gathering neither a football thread for him, as you do not want anyone discussing his performance. Which is your stance, thats fair. However, whether you like it or not he's a United player out on loan, there is an interest in his performances and this is a United forum. You should not censure discussion on his performances just because you don't like it. By all means ban those that are breaking forum rules, however, closing threads or shutting down discussions on how a united player is performing on loan for me is not right.
It is opinion, I've posted regularly about his performances and when I challenge people on showing posters that have broken rules etc there's no reply or I get shown the one user whose been banned when there have been many more discussing his performances rationally. The reality is he's a talented footballer, that has not changed. He's going to have games where he looks good/great, when discussing him as a player breaking through you are going to talk about how he looked like a worldie, guess what? That's part and parcel of discussing a player's performance. On the fawning I personally don't think there are posters going overboard with fawning, however, if you think people are overrating him fair enough, keep the same energy for those who were saying he was overrated as a youngster. Either way, that's part and parcel of a player performance thread.
To me it seems you just want a thread where the only discussion allowed is to confirm that Greenwood is scum etc etc. If that's the case maybe someone else who is able to be level headed should manage this thread.
