I genuinely do have trouble unifying my instinct that nazi propaganda, for example, should be censored, against my understanding that what constitutes "solicitation to commit crimes" is relative to what a society considers "good" or "bad," which is (somewhat) arbitrary.
Take your list as an example. Any action that is damaging to the State could be considered Criminal - perhaps something as simple as developing good cryptography, for example. Some things are crimes that shouldn't be - smoking marijuana, an example. Simply saying "solicitations to commit crimes should be censored" thus doesn't jive with me.
I think the main problem is the human heart ... but that is a different discussion.
What if it's against a group of individuals?
Claims like this--and these are the tip of the iceberg--target groups of people and affect every individual within. It's like passive libel/slander that every member of the group has to contend with.
It can even affect people outside the group. I don't think I know of a straight man under 30 who isn't afraid someone will think they're gay if they do the wrong thing. And more than a few cisgender women get run out of bathrooms because they present in a more masculine way.
