Nobody said 'reverse racism'.

The person you replied to was clearly talking about racial stereotyping. The objection was to the stereotyping.

A video that debunks reverse racism is not an appropriate reply to what is (at worst) effectively a typo. s/ist/ial/ and done.

Guessing that someone arguing from an obvious position of privilege is a white guy is only a racist stereotype if you believe reverse racism exists.

...you're ignoring what I said. Ignore the word racism. It's objectively a racial stereotype to call someone's race based on the way they're talking.

Arguments about the term 'racism' don't matter. He meant 'racial'.

The person is a racist, its not worth arguing with one. They feel that their stance is the only valid one.
