I don't think of BM as a 'rivals website' more of a 'football forum' where there's actually a lot more interesting chat going on than on other sites. Yes I know City are a rival but that's not why I'm here.
Re being mentally unwell - well most men have mental health challenges at some stage in their lives, I'm sure I'm just as likely to as the next guy and if I did it wouldnt be anything to be ashamed of.
I will say though that on forums where people display overt hostility to complete strangers that's often a sign that all's not always well with them on an emotional level - I'm not having a go as honestly it genuinely doesn't bother me getting flak as I'm getting it from people who've never met me and therefore don't know me - they might just as well be shouting at a cow in a field. But I'd question why hostility seems to be the first port of call for some folk anyway and what's behind that. Because being unpleasant to someone often makes the recipient feel bad, but just as likely makes the giver feel uptight as well. It's easier just to chill IMHO - it just feels better.
