Canadian professor Jordan Peterson is a lightning rod for controversy, so it was inevitable that he’d be locked out of Twitter eventually. Twitter says he violated its rules against hateful conduct with his tweet about pride and actor Elliot Page (whom he “deadnamed”). We’re guessing it was the deadnaming (he called him “Ellen Page”) that got him the strike. Here’s the text of the offending tweet:

Remember when pride was a sin? And Ellen Page just had her breasts removed by a criminal physician.

Twitter doesn’t mess around when it comes to trans issues, where virtually anything can be considered hateful conduct.

When did the term “deadnaming” come into being, anyway? We remember hearing it bandied about a lot when Chelsea Manning was in the news.
