Right, because conformism is just the backbone on a strong and healthy democracy, ain't it. Whatever happened to liberty, individual rights, personal choice, critical inquiry? I do what makes sense to me, and avoid doing things that interfere with others' pursuit of happiness. I expect others to do the same. That's not "personal greed," that's liberty.
Why should a Southerner conform just because they're in San Francisco? Sure, they shouldn't go around insulting people, but many bigoted Americans, Southern and otherwise, are very nice, unobtrusive people (on the outside, at least). If they want to open up a chapter of the Daughters of the American Revolution here in SF, start country bands, whatever it is that they do, why not? As long as they're not making life hard for others, I don't see a problem with it.
As far as I'm concerned, weirdness and individuality ought to be cultivated; people should be concerned to critically evaluate and shape their own lives, and do what they find enjoyable. It's not "greedy" for someone to pursue whatever path in life makes them happy, as long as it does no harm to others. Mindless obeisance to the dominant culture makes for zombie people. It is important above all for people to pursue knowledge, critical thinking and analysis, and to be self-cultivated, self-realized and self-aware. That's what liberal representational democracies are all about.
I wouldn't go to Iran, because I'm not willing to cover my hair, and I'm not about to get myself thrown in jail for that. If I were to go to Turkey, though, I certainly would not cover my hair.
This is why I'm opposed to laws banning burqa and niqab. To me, feminism is about personal choice, and robbing women of the choice to wear "modest" clothing is almost as bad as forcing them to wear it. Culture be damned - people deserve no less than to be able to pursue their own happiness, and live up to their own values and standards. For some people, that's wearing a niqab; for others, that's dying their hair green and getting tattoos on their knuckles and up their neck.
Whatever lifts your luggage, I say...
