Yup, zero questions in my mind. If anything the US is currently too strict when it comes to abortion.
The US is one of the least strict nations when it comes to abortion. I think China and North Korea are the only countries with less restrictions.
China and North Korea have less restrictions (especially in practice, as Tony points out) if the lens of analysis is 'how easy is it to get an abortion?', but vastly more if the lens of analysis is 'how easy is it to freely decide whether or not you want to get an abortion and safely carry out that decision, whatever it is?'. I think this is an important distinction, because morally serious pro-choice people are interested in the latter question, not just the former.
To answer the question, I'm not any more (either by the stupid leading definition in the OP or by the fairer definition of 'erring on the side of laxer abortion laws in general'), but I'm constantly going back and forth on
how 'not' I am because I think there are still compelling moral and practical concerns on the pro-choice side.
