Jon66 Sounds like you agree with me that boycott of Israel is not discrimination, but claim that banning of Palestinian professor is similarly not discrimination either. I guess we are half way there.
It is clear that the professor is banned, not because of the tone, but because of the content of her posts. She was banned to suppress information about discrimination and slow ethnic cleansing of Palestinian individuals by the state of Israel. I suppose that banning someone to enable to enable and protect discrimination is not discrimination on the narrowest of technicalities.
