Wait, so some person reads a twitter post of someone commenting on kids going through sexual reassignment surgery and how they consider it an issue.
They find a project they're associated with. They go on it's github repo and they start an issue with a title of "Transphobic maintainer should be removed from project". Not "Potentially transphobic maintainers and how their association with the project hurts it in the long run". Not even "My feelings were hurt after I interpreted some comment of one of the maintainers in some way, please let's discuss". No, they simply demanded removal of someone, based on an, at best, ambiguously "transphobic" twitter comment.
And you're here telling me that person isn't the one with the problem.
