It also supports the manchild phenomenon, the idea that it's normal and appropriate for men to grow up much later than women and to be facilitated by women for as long as they think they need. Where were most of us at 20? I'd already moved to a major city in a country I'd never lived in before, found a flat, moved myself into it, and generally managed by myself for a couple of years. People fight in wars at that age. They get married. They have children of their own.
Were any of you in the habit of donning balaclavas and physically intimidating people in an attempt to deny them the right to free speech at 20? Would it even have occurred to you that you had the right to do so?
This person is not a vulnerable child, they're a bully. Perhaps they will eventually learn not to be, maybe they'll even develop some trace of respect for women, but given that they still believe that it's up to them to decide whether or not they should let a woman speak it's not looking great so far.
