What is the 'white male position'?

If this argument was moved to, say, Nigeria, would there be a problematic 'black male position' there?

Expectations about what constitutes being qualified for leadership positions. The automatic deferring to old men as authority figures over other people (trans people have direct experience). The way most many carry out competition. The idea of stoic sternness as being the ideal. Tone and voice.

Trans people who express themselves as male have a ton of interesting anecdotes about how they were suddenly seen as more competent just for being men.

Is this exclusive to white society?

If anything the whole macho leadership thing is even more apparent in less developed places.

Yes absolutely. Mugabe of Zimbabwe is well known for illegitimately taking land from white farmers and forcefully redistributing it, and has been repeatedly called out for this. We shouldn't be surprised that when a President has more to do with Mugabe than Reagan that he will be called out on it.
