Let me ask you a question. Should your comment be censored?
> You're going to have a hard time convicing me that any of these are mutable.
Hate speech (and violence).
> While the presentation of sex and sexual orientation may be mutable (someone can be female passing or straight passing) their orientation or sex itself is not.
Transphobic. Homophobic.
> Similarly while someone can be white passing or codeswitch, their race itself cannot be changed.
Racist.
> doesn't mean that I can stop being black or white or whatever, at least not without convincing society to change its definitions.
... proving my point? They're not objective criteria. Which means you aren't censoring "immutable characteristics". You're censoring political speech. Opinion and group identity are mutable and they are the basis for hate speech definitions.

If you don't think you've made three hateful statements in one comment then you haven't been paying attention. This is where the political debate is. If you're ignorant of it then you have no business appointing censors.
