To have advice I'd really have to have more specifics. Like, just because we accept ourselves as we are, including having Asperger's, or aspie traits, doesn't mean we don't have things we should change. And Christianity is about spiritual growth. Or, it should be anyway. That's really the heart of it. Being a Christian does not mean being content with who one is. It means growing in one's spiritual life. (And, even if you don't see Christianity as I do, it's significant here because the Christians you are talking to might. Not trying to start a religion debate -- that's for PPR -- just bringing up issues relevant to the thread.)
If they are being judgmental, you could point out that Jesus told us not to judge. If it's a misguided attempt to help you in your spiritual growth, you could gently (or semi-gently) tell them that they aren't meeting you were you are at.
You didn't mention how you know these people. That makes a difference too.
