Wow, yeah man, referring to an attempt to exterminate a population as a genocide is definitely just as bad as calling for the extermination of minorities. That's definitely the same level of morally wrong.

Like, this is literally my point, "abolishing the police" may not be the most effective way to build a better society, but there's absolutely nothing morally or ethically wrong with saying it. If you don't get this, I'm genuinely not sure how to explain it, but here's a short attempt:

A police force/buildings/cars/employees are an artificial construct created by a series of laws passed by a (in this case) democratic government. Repealing/passing new laws that removes the police system is just a neutral action in the same way that creating them in the first place was.

People say "abolish the police" because they genuinely believe it will help everyone. People do not say "deport brown people" because they think it will help everyone. You get how this is different, right?

Also, lol, you said "cancelling people" like it was a real thing. What happened, did someone have an invitation rescinded because they said something offensive? Wow, yeah, uninviting someone is definitely some kind of awful moral hazard. That person was entitled by his existence to give that speech, dammit!
