The problem with the question M3J is that it is too wide and general. As you are doubtless aware Europe is made up of many countries with differing histories and cultures regarding religion. Its hard to generalise Europe in the way you are looking for, and any such generalisations will be seriously flawed. There is a few things that can be considered though, surveys and polls have been conducted across Europe (usually by the EU) to try and gauge the general religiosity of the population.
This is a Gallup poll held in 2004 on religious service attendance. There are other polls on this
wiki page about peoples views on the importance of religion in their lives .
From the surveys there are huge differences, some countries as a consequence of their history and culture are very irreligious (the nordic countries in particular) while others are not (Mediterranean and catholic states). However it can be safely said that socially in a lot of countries religion is not as big of an issue as it is the United States.
The other statements you made will differ depending on the country. I can only speak with authority on the UK. The UK is one of the few non-secular countries in Europe, the monarch is the head of the Church of England and church officials have seats in the upper house (going into more detail into this will just get confusing). The country is socially secular however. Abortion, creationism etc are non-issues, full and legal gay marriage is almost reality (there is currently a thing called civil partnerships which is marriage in all but name). Religion being used as an argument in itself does not happen on political issues.
Having said all that however religion is still a controversial issue itself. The only difference is that it is no longer used to justify policies. Religious intolerance still exists in parts of the UK. This is all anecdotal so bear with me, there are problems with extreme nationalistic right wing groups who still see Christianity as being a national heritage and are intolerant of other religions (the most vocal opposition to being Islam) and on the other spectrum intolerance from religious people towards people against their belief system or those who oppose it (mainly from radical islamist groups). Both are however extreme examples and are not popular positions within the non-religious or religious populace.
Personally I think you are beating up the US a tad too harshly. You do have some extreme groups, and for a secular nation, a huge hang-up on religion in your politics. There are some intolerant places in the US but the same can be said for Europe, the grass is not always greener on the other side.
...However, its probably better for your blood pressure to be atheist in Europe than the US.

Also bear in mind when I speak about intolerance in Europe our most extreme cases (Srebrenica which occurred in the heart of Europe) will almost certainly never occur in the United states. It really does differ depending on where on the continent you are.
