Everton fans are not the problem. Society is the problem.
There are far too many instances of people not knowing how to behave in society. This is not an Everton or football problem.
I think from an Everton perspective, there is a lot of negativity about the club and that can bring out some horrid behaviour from some. I am sure if we were 2 up and the same happened you would not hear the same abuse, but the personality of these people would still be there just waiting for that opportunity. Blame it on drugs and drink, possibly, however there is still an underlying nature of society that just want to be nobheads.
