ok, I would rather argue that the woman is wrong in her case.
So how do you know to distinguish a valid criticism from hate speech?
Easy:
Valid criticism usually has some kind of humanitarian element to it.
Example: Israel are nothing more than murdering pigs for the occupation of the West Bank, denying Palestinians basic human rights, and destroying settlements that have existed long before Israel did, thus the inhabitants have more right to the land than any jew. Let alone the slaughter of innocent children.
That's a valid criticism.
Hate speech does not have any validity and is just an attack with out reason. Example: I'm going to kill any Palestinian because I hate Arabs.
Or:
Individually, Israelis lack the social skills to be allowed in to civilised society, and as a country, they should be barred from the United Nations given their inability to co-exist peacefully with their neighbours. They are no better than some IS scum bag. Ooops. My mistake. That was actually valid criticism. I understand why you had to ask the question - it can be difficult can't it?
