I agree with that position but I don't think SDS's post is saying he's a better fan than any other.
It gets old having to defend the team you root for when you're supposed to be amongst fellow fans, especially when there are some posters who do nothing but bash every single move that is made. No one will like all of the moves, that's a given, and that's fine, but there are some who seemingly hate everything and it seems the only joy they get is in putting the team down. After so long it's only reasonable to ask why they watch the team still or suggest they find another hobby because clearly they get no enjoyment from the Suns any longer.
I'm surprised to see a mod step up and quote that rule here in this instance because of how that post came about. I don't see how a fan that is enjoying things, or trying to, asking others who aren't why they still watch deserves a warning when the opposite happens without note quite often. By opposite I mean when a poster questions another's dedication as far as why they still watch the team when they'll only be let down and how they're a homer or an apologist. If either were to cause a mod to step in, like you have here, I would think it would be the latter rather than the former.
This is a Suns forum and as a Suns forum I think it's reasonable that a Suns fan could ask some that post here why they're following the team if they don't enjoy it compared to someone asking posters to defend their allegiance to the team because the team sucks.
