So apparently he criticized Israel -- which you can do in Israel, but not in the US. It's not worth the drama to discuss any of that.

You certainly can do it in the US. Perhaps something special about the (sub) reddit thread?

Sure, you can, but it's not politically acceptable by either side of the political spectrum.

The whole discussion (incl. drama) seems fairly interesting. I wonder if anyone would be up to editing it into some sort of coherent article, as of now following all the links and deleted/edited content makes bit difficult reading experience.
