You might not know, but hardline Sunni Muslims are very racist towards Jews. They regularly quote verses from the Quran and Hadiths where Jews are incarnations of satans and should not be tolerated.
They also regularly quote anti-non Muslim quotes in social media calling them Kafirs.
If you live near a significant population of hardliner Sunni Muslims, you'd know this.
Bengali social media is filled with such rhetoric. There were open celebration of the French teacher getting beheaded for the Muhammad cartoon. Seeking the death of all Jews is very common.
Such posts deserve to be removed.
You call for death of an entire ethnicity, that is valid reason of posts getting removed.
