I've no idea why some posters spend so much time talking about, and even sneering at, other posters.
It's football. Talk to 10 people around you at a game and you'd probably get 10 different views on it. I don't really get to games currently but read the opinions on here, positive and negative. They're all valid, just opinions.
Plus, people have other stuff going on in their lives and that can impact how they post. I've definitely been arsier on here when other difficulties have been going on, we're probably all the same in that.
Cheltenham summed everything really well in his/her earlier post regarding the mindset of many supporters.
