This whole “black voters are pro-life” thing really isn’t true. Pew Research found that 66% of black protestants support abortion, higher than any other religious group. Meanwhile white evangelical protestants are the only group with a majority opposed, and a supermajority at that:

Abortion really is not the same as certain other social issues when it comes to black voters being more conservative, even the religious ones.
