Personally I also do use the term pro-abortion because it is clear about the actual issue and what the disagreement is. Pretty much every single person anywhere is in favor of both life and choice, it's a uselessly euphemistic set of terms that obscures the real conflict.

I'm not necessarily in favor of any specific case of abortion, or wanting more of them in the world, or anything like that. "Pro abortion access" would probably be more technically correct but that opens the argument up to getting derailed by "well how much access" and shit. Plus the mild transgressiveness of the term is helpful sometimes, if it makes people stop for a second and ask like this.
