I actually WILL do stuff I like regardless of who else doesn't like it or does like it.
However, it really pisses me off when something I like becomes a fad. I'm afraid it will get dumbed down by people into something it's not, or liked because it's a fad rather than on its own merits... you know, people wouldn't have liked it at all, except it was the in-thing to do.
I'm concerned about the Maleficent movie coming out, for example; I think she's a great character, and at least AJ looks pretty good playing her so far, but I'm afraid that the character will be mishandled... kind of like in Oz the Great and Powerful, where the Witch was just kind of butchered (although the Wizard and Glinda were treated decently).
I didn't like it when Inception became so faddish. As long as people liked it because they understood it and grasped the depth of it, that's cool; but if they're just hopping on the bandwagon on the next property to be exploited by American consumer culture and NYC advertising, well, fuck that.
I've also watched other things I've loved become raped by western consumerism, like Watchmen and V for Vendetta. It's not a pleasant feeling. You can say it's less me being a snob and more me defending the honorable of something I viewed as special and deserving of real effort to portray and understand it, instead being given a lobotomy so it could be mass-marketed as the next cash cow property.
There's also something to be said for working hard to find something special, earning the right to savor it... and then someone just peddles it to a crowd who won't give a shit about it in a month but right now it's "popular" and they'll just use it, consume it, and then dump it for the next thing. It's kind of a gross process to observe. It used to be a big deal to scale Mount Everest, but not anymore... and now the entire mountainside is also covered by piles of shit and trash that the consumers have left there because they never had a reverence for the mountain anyway. It was just one more experience to purchase on the backs of the people who earned the right to climb it, and then they move on to the next thing to be consumed.
I don't think those kinds of feelings I experience are elitist. It's more that people aren't really valuing something I consider precious and deserving of effort to grasp. But unfortunately that is how consumer cultures operate; they just eat anything that looks like it might taste good and shit it back out as they're looking for something else to eat.
@Saudade: Yeah, I understand what you mean by "being copied." You like it because you like it; they're just copying you because it's cool. It DOES feel like having your identity made irrelevant or trivialized in some ways. (As a minor example, Inception really resonated with me in some deep-seated ways, but I feel like I can't claim it as part of my identity because it's become so watered down as to be worthless as a descriptor even if it should actually be powerful.)
