The question is 'Why?' not 'Why not?'
Who if they wanted to have children would be in the least bit interested in what skin colour their children had? Also if you are having kids in the belief that it somehow enures your immortality you may not be the kind of person who will prove to be a decent parent. Kids have enough on their plate without having to deal with some egotistical self obsessed parent.
For sure i can waffle, but is is very funny that you could, without any irony, post such a garbage nothing burger video, and then accuse me of waffling.
