@tessaracht ooh. I know you're upset but it's not cool to call people of a certain ethnicity, gender, or sexuality cancer, even if it's privileged cis white men. This guy was an asshole. No group of people is cancer.
We shouldn't tolerate people talking about us like that, so we should definitely not do it to others either.
Also, we shouldn't assume people's sexuality or cis/transness, or that such would have anything to do with their behaviour.
