I am "pro-life" but like you, I'm not so sure government should be involved overly much, at least in regards to early term abortions. I just don't think it is helpful.
On the other hand, what is the role of government? If it has a role at all, is it not to protect rights? What right is more important than the right to life? At what point does a human gain that right? Just something to think about.
