Yeah, I've been on both sides of it - enjoying getting my snark on while my fan-friends still like something, and still squeeing over something my fan-friends dislike - and it can be uncomfortable on either side. As you say, being out-of-step with fandom is no fun, especially when you're rooting for something different for a show than everyone else. It's a similar thing to loving the pairing that everyone else hates on...even if it happens in canon in the way you want it, it can be a little sad if everyone else hates on it. These days I generally just try to find fanning circles that match my basic feelings, and avoid places/discussions that don't...
