There are no "neutral" names for advocates for or against various policies on abortion. I'm fairly sure our Wikipedia articles on [[abortion]] make this clear.
I have chosen therefore to use the terminology the two main camps have chosen for themselves, when referring to them:
* pro-choice * pro-life
The "pro-choice" camp generally favors loosening of restrictions on abortion.
The "pro-life" camp generally favors tightening of restrictions on abortion.
If the above info is not already in the Wikipedia, it should be put there.
