Abortion question....

Someone asked me a good question....The largest demographic of those who receive abortions are single African American women. If you are against abortion, does that mean that you are inherently for Black Lives matter? If you are for women's rights/proabortion, does that mean that you are inherently against BLM? Banning abortions allows more single African American women to have their babies which is consistent with the BLM movement. Thoughts?
