I'm not following you, you just keep appearing with your missionary work in the same places I happen to be. So I'm making the best out of it by having some fun. And by the way, jews killed jesus is a popular antisemitic trope.
They do seem to pop up like a Jesus-in-the-box in every thread where someone brings up Christianity. I ought to have blocked them by now, but it's kind of fascinating. They're less aggressive than your garden-variety tankie, but just as stubborn and dogmatic.
While that user is not the only one I have tagged as "feckin crisso," they seem to be the most prolific of that stripe at the moment. I was using the singular they.
I had a longer conversation with that dude, just check his profile - he is really deep, like Jesus und Satan are real deep. So I would not be surprised if he peddeled the classic Jews killed Jesus trope. I'm still not sure he is not.
