Let me provide an example: Dinner's criticism of, and antipathy toward, Islam.
Islamic shari'a law mandates the persecution of religious minorities, the oppression of women, an actual rape culture, pederasty, oppression of gays, and other, similar, barbarous acts.
Muslims are a polyracial group.
Yet Dinner, for criticizing this barbaric, backward, viciously oppressive theocracy, is regularly labeled by Leftforge as "racist."
Never mind that Islam is polyracial. Never mind that it's the behavior rather than the ethnicity of its adherents that he's condemning.
They're perfectly content to dishonestly misattribute the focus of his condemnation and then -- based on their conclusion about what his race is -- label him "racist".
But, in fact, those condemning him are the racists. They're engaging in the racist assumption that adherents of Islamic law are entirely, and exclusively, Arabic. They are engaging in the racist assumption that race is the basis of Dinner's condemnation of a vicious, oppressive theocracy.
Dinner is not the racist. The simple-minded Shari'a apologists on WF are.
