If you want to be play old-school games, play old school games. If you're excited about D&D Next, that's cool too. It's okay to love Tom Baker and Matt Smith. You're not a poser for wearing a Green Lantern shirt while reading a Spider-Man comic. Just because you like one thing, doesn't mean you have to hate another. It's okay to only like one thing. It's okay to like a multitude of things.
It's not cool to make other people feel bad for disagreeing with you.
