Actually there are many more possible position in the abortion debate than pro-life and pro-choice. The fact that the position exist like this in US society is a result of the fact that the issue didn't get resolved democratically via congress but via the Supreme Court.
Different European countries have different abortion laws and it makes sense to discuss with laws around the issue are best. If you want to have a senisble discussion about the topic, don't treat it binary. You look at a bunch of different legal solutions to the abortion issue and start comparing which laws you prefer over which other laws.
Restrictions on procedures can take a lot of shades, but the basic choice of yea or nay is pretty binary. For comparison, Canada also had abortion law determined by the Supreme Court(it was legal but heavily restricted before, and now we have literally the loosest abortion law in the world - there are no restrictions whatsoever), but the issue is nowhere near as controversial. I think the difference has a lot less to do with the Supreme Court, and a lot more to do with the US level of religiosity.
As Multiheaded added, "Personal is Political" stuff like gender relations, etc also may belong here.
