Literally nobody commented on the actual content of the OP.
That's what I mean by defining the default. The default, in your point of view, is the word "man," so therefore anyone who objects to that must be "different" in some way: overly sensitive, manipulative, deficient, etc.
When in reality, "man" is the default because men made it the default. That doesn't mean that it has to remain the default.
I'm not suggesting that we go back and edit Neil Armstrong's words--they were of their time and are amazing. I'm suggesting that we're in a different time now, and starting now, it is within our power to choose the words we use.
The idea is to recognize the history and context of language, not assign all problems to one word. No single drop thinks it is responsible for the flood, etc.
