I think it’s fine to have rules that address actual problems and ignore imagined problems, even if they are not gender/race/whatever protected class-blind.
Men feeling unwelcome in internet spaces due to body objectification is not an actual problem that men face, so we don’t need rules to deal with it. In contrast, the corresponding issue with women is a major social issue, and we should take steps to help improve things.
Like a recent discussion of whether the term “cracker” should be banned in the pit because the n-word is. One of those words has a deep hateful history, and it’s the one we should ban. The other one no one really cares about, and having a policy that treats them as equivalent is just a silly veneer of consistency.
