Evidence of what? I was asking you if killing blacks is the only reason you are so pro-abortion, that is a question of your personal opinion.
Here, let me explain the situation to you:
1. blacks do the most abortions, black women have huge amounts of children out of wedlock
2. If that were not the case the amount of black voters would massively increase and we would have a democratic party monopoly in the country
3. And that in turn would mean no more bans on abortion
So in other words, your group that does the most abortions would eventually grow and make sure that NO anti-abortion laws would pass
