On an LA station’s FB thread about this there was all kinds of speculation about who to blame. There were a few saying it was Libs, but mostly claims the perp had to be MAGA and/or anti-abortion. Being the jerk I am, I pointed out that neither pro-aborts nor Pro-Life people strongly hate IVF, and we (at the time) knew pretty much nothing of the perp’s views. The Hate-Trumpers and pro-aborts went nuts, and at least a couple went ad hominem.
I enjoyed the schadenfreude of posting the NBC article about the perp’s actual views.
