Here are a few facts that might surprise you - about Belgium, but they're not necessarily that different in other West-European countries.
- Share of children attending religious schools: 60 to 70% as I recall
- Wages of priests (and rabbis, imams,...): funded by the taxpayer (thanks to, believe it or not, Napoleon)
- Churches or priests harassed or forced to perform gay marriages: none that I've ever heard of
- Abortion law, just for the heck of it: illegal after three months, with exceptions for rape, incest, health of the mother and the child (and even that law required a constitutional crisis to get passed back in 1991)
I think Americans are a bit too quick to assume that Europe or at least Western Europe is anti-religion somehow. Religion is still very important and in some ways more closely embedded in the state than in the US; but perhaps exactly for that reason, it's a lot less polarized and controversial, with progressives feeling less antagonized towards it. Abortion is a lot less controversial not because people don't care about the issue as such, but because around here abortion laws are painstakingly wrought compromises, instead of the lightning rod that is Roe v Wade.
