it was sexist in that it pertained to the sex of the human species... that basketball player is a man in two ways... he is an adult male... and he is of mankind... in the second aspect, it does not matter what sex he is... humans are "man." just as transgenders and transsexuals claim to be of a different sex than the one in which they were born, DNA says something else... manhood is a stage that males reach at a certain age--when they are adults... it has nothing to do with their actions...
adjectives come in handy when the desire to differentiate rears its head...
Funny! I believe we both know that I was speaking of a mindset, of being men in thoughts and deed not in biological, physical attributes, just as being a Mother is more than the physical ability to squeeze a baby out of an orifice. Thank you for the philosophical ride down the rabbit hole but it changes the obvious intent of my comment not a whit.
