I am anti-abortion. We should work to minimize the number of abortions. No one is "pro-abortion". An abortion is a medical procedure that results from a failure to avoid getting pregnant. In that sense, it is like heart surgery. No one is "pro-heart surgery". Heart surgery is necessary only because other conditions have not been handled so that it can be avoided.
I trust people. No one gets up in the morning and thinks "I need to get pregnant so I can have an abortion". No one wants to have an abortion. So the best way to handle abortions is to create an environment in which no one thinks that they need one.
The best way to do this is effective birth control. There are lots of ways to do this, but the objective should be to make sure that everyone knows about birth control and has access to as much birth control as they need. Education and access can prevent unwanted pregnancies and thus eliminate the need for abortions.
