Here's a thought and a challenge, if you personally think that people who've never been football managers for example should keep thier collective mouths shut about football - maybe the next time there's a major game going on - you should go to a local sports pub and tell all the fans of both teams that they are special snowflakes who have no rights to complain about the state of the game, because they've never been footballers.
No, what I am saying is that hanging around a clubhouse and slagging off the team for years without going to the matches is strange. People are likely to suggest you find a club you do like, and actually support them in the matches. Because that is kinda what it is all about. Also, football fans generally dont expect anyone to do anything with their opinion, I know I dont expect management to do anything with my eloquently voiced suggestions during the match for starters. So sure, you can talk about whatever you want, whenever you want, however you want. I am just pointing out to you that to the average person it would be considered rather odd to hang around a forum for a game you have never played for half a decade or so, or even once since launch. You can do so, but if you want to know why people find it odd, this is why.
And if that 'makes it personal'...
