So it’s pretty ridiculous how many times I’ve heard this:
If you want to understand a pro-lifer’s perspective, take any argument about abortion and substitute “fetus” with “3-year-old.” Try this with me:
“If you don’t like killing 3-year-olds, then don’t kill any. But don’t try to impose your beliefs on me!”
See what happens there?
The fetus is a human being, and pro-lifer's consider the fetus worthy of human rights/protection. The "don't like one, don't get one" sound bite ignores this fundamental pro-life belief. It makes no sense to tell people who believe human rights are being violated to mind their own business.
