The old testament also banned eating shrimp and that people working on Saturday should be stoned, so I kind of see lots of cherry picking here. It's also highly ambiguous if the fetus should be considered a human being or property (see Exodus), but that's not the point.
The core point was that most of the message and teachings of Jesus were clearly, unambiguously about social justice and charity, and yet modern Christians care way more about Old Testament moral rules than the actual Christian message, what Jesus clearly cared about the most, the last, the meek, the poor.
The modern Christian votes for racist ultra-rich that only profess hate towards everyone that's different from them in order to get abortion and gay marriage banned. That's the worst corruption of the Christian message possible, in my opinion, and makes those people phony believers to my eyes. They use their as an indentitarian way to distinguish them from the others, which is absolutely at odds with the ecumenical message of Jesus Christ.
Care about the young not being able to start families first, about those who are in need and can't make their ends meet, and then take care of the rest.
