I never quite got why that is a bad thing, granted I can not see it being a positive thing (unless you are betting), but it is nothing I can see being especially riled up about.
Yeah perhaps. I guess its just that because I'm part of the older generation it used to be somewhat different maybe 25 years ago. You picked your team back then on affiliation for the most part. For example you live in an area close to a team, family ties etc. Nowadays its not like that. You'll get idiots now who when they find out you don't support one of the bigger sides in the country will be like "why do you want to support "x" team for, they are shit". Supporting a team shouldn't be about whether they win everything year on year.
But then these same people will don an England shirt during the tournaments spouting "its where we come from" even though we don't realistically ever have a chance of winning anything. That's the point where I come out and say something like "so why don't you just support someone like Spain, Germany or Brazil, who are more likely to win" and they look at you gone out!
