> Once you start judging them (for actions other than abuse and neglect), you very quickly realize how limiting that is.

"Judging" is a bit of an overloaded term. I don't think it's OK to call someone human trash for having a risky hobby.

I do think people can say, "You're better than this. Make better choices."

One version is dehumanizing someone for their behavior. The other is (when phrased well) constructive criticism.
