They also are against gun control, and generally favor allowing police to murder freely, provided the victims have brown-enough skin..
So, no: their politics are very, very far from consistent.
Everyone's is. Politics is tribal, not logical. Take every single political tribe in the history of humanity, starting with Ancient Greek city polities and ending with modern democracies, Russia and the Islamic state, and examine their beliefs. Contradictions are rife.
For me, the lesson is that if you value your integrity, you shouldn't join a political tribe. ANY of them. Green, red, blue, yellow, these are all a loyalty-first, thought-maybe-later groups.
That begs the question. Beware of trying to fit and squeeze every phenomenon in the world into your own prejudices.
My experience with the pro-life crowd is that they really consider abortion on par with murder and that is what motivates them to fight on. Even in a country like mine, where abortion is widely accepted and pro-life positions won't help you electorally or socially at all.
