When flagging a comment, one of the options is
It contains harassment, bigotry, or abuse.
This comment attacks a person or group. Learn more in our Code of Conduct.
and the quoted section of the code is
No name-calling or personal attacks.

We don’t tolerate any language likely to offend or alienate people based on race, gender, sexual orientation, or religion — and those are just a few examples. When in doubt, just don’t.
This includes, but isn’t limited to: bullying, intimidation, vulgar language, direct or indirect threats, sexually suggestive remarks, patterns of inappropriate social contact, and sustained disruptions of discussion.
Does this reason cover attacking, or inciting unlawful violence against, someone who isn't a member of the site?
My understanding is that the "No harassment" section is most likely to be relevant, but I want to check.
