I can't speak for Europe as a whole because Europe isn't one country, it is (surprise surprise) a large collection of many countries. I get the feeling that by majority (especially in the UK) it is frowned upon, but freedom of speech dictates that you can say it if you wish. I wouldn't say it myself because I know how many people it would offend deeply and I also don't agree with deniars. Not that I know their full reasoning, but it seems an odd thing to deny the happening of.
