It 'is' different, and you weren't.
The debate isn't just about whether folk want to stand, or are prepared to stand, but about changes to current stadiums, and indeed laws, in order to accomodate. We've all stood at a bar too, or at a bus stop, but that doesn't justify doing it anywhere else, and is irrelevant as a 'for'.
It's a spectator sport, and as such, each ticket holder has a right to be able to view the game in which they paid for, unrestricted in view, and in a safe environment. No amount of signatures will change the principles behind any decision.
We live in an age of risk factor statistics and prevention. All the smokers in the country could sign to return smoking to pubs, but as long as the government make decisions in a 'what if' line of reasoning, it will never happen.
The best thing for fans to do is to accept the current legislation, and try to come to terms with it as such that it becomes less of a burden. We all have preferences, and I do sympathise, but it won't happen.
