Not in my experience. All the christians I've known over the last decade have been lovely, welcoming and open. They do have their in-groups too of course, and my interests are particularly bohemian so we don't socialise all that regularly, but honestly their religion only tends to come up if I ask about it. Otherwise they're just as content as anyone else to come and see a movie or go for a walk or whatever.

Some of the old biddies at the church I grew up with were pretty judgmental though, but they're all dead now. Everyone left is just... nice.

I only know Muslim parents through my kids school, because my kids best friend is Muslim, and the parents are perfectly happy with playdates with my secular kid. There are one or two cultural oddities - e.g. the mum won't come over our house unless my SO is also home (but will meet me in public) but I'm not sure if that's a Muslim thing or a Turkish thing.
