Is it normal i don't want too many muslims in the country i live?

I mean, I'm not entirely against them coming here but they're kinda destroying our culture. See, we are a Christian country with all feasts being a reminder of our history. The buildings that we have, some are over hundreds of years old, belong to our culture as well.
But then there were lots of refugees and the country I knew changed. Beautiful old buildings are destroyed to have the place for a mosque or are inhabited by Muslims now, of which some are arguing that it's not big or warm enough. They say if we have our feast then they shall have theirs. Some of the kids are respectless and others from our country think it's cool and do the same things.
As I said, I'm not entirely against Muslims. I know a few who are really great people. But we can't have a fly to, for example, Turkey and destroy old buildings there to build churches, say there have to be Christian feasts where we take a few days off working and tell their teachers they have to learn our language. Excuse me!?
