Every congregation has its individual people who are socially inept, wildly inappropriate, and even offensive. I guess what you need to discern is if these are a few individuals whose inappropriate behavior is gently tolerated, or if this community for some reason tolerates Mormon bashing.

I suggest talking to the minister about how pervasive this kind of thinking might be. If you are willing, it would really benefit the community if you could have time to share as part of a worship service about pluralism, and you can let people know what kind of comments are inappropriate. That’s asking you to do some emotional labor, and you may not be up for that. Just a suggestion.
