Whenever I read A&H when race and the word "nigger" comes up, it is a fancy way of saying "people who dont act how I like and also not my skin color". Appending "sand, white," etc. on top of it, followed by "chink" which is it's own 3rd party because the chinese are foregin in mentality but successful and "jew" for white people who are successful but are doing something wrong with jewish ancestory.
There are so many disappointing degenerate white trash people who aren't any of the categories above that it kills me every time someone says "onky a nigger would sell their baby for crack" and if you bring up they were white they'll just say "yes a white sheboon nigger". You'll see the same with hard black groups calling someone black who acts against them an oreo, a coon, an uncle tom, etc..
Race has important cultural and genetic stuff tied to it (like sickle cell anemia) but most of the angrier people who talk don't care and are venting their tribal mentality anger. Sure you can call people whatever you want, but if you're constantly calling people one insult because its the most offensive thing you can think of it changed meaning from "very negative stereotypical black person" to "anyone who disappoints me" (same for "white just means not with me on opinon" hard sjw and black power crowd). You have to keep your slurs separate from each other for a reason or else they stop being slurs and start being your own go to chimp out words.
Beyond that, race can be very interesting to talk about. I 90% go with what the person says they are, followed by their actual culture and genetic records and how people treat them, which is the main factor of separating races I feel.
My take is that its ultimately like the varieties of roses: different colored and different looking with different needs and different ways of occuring, but still a rose. Humans are just more offensive than roses because we have the capacity of free will and though, and some people will choose to be bastards or group up and become team bastard etc.. But they can also team up and create cool shit and have bomb ass meals and art culturewise. Hyperfocusing on the race is only important in genetics when determining possible diseases or for tugboat money, which is probably the heart of most racial fighting. The two examples of children you give will be called white or black or what have you when activist need someone to prop up as X but be forgotten about as soon as money comes into play since the children are well off. "She's not black she has money" is a hyper retarded line parroted by both sides.
Follow your instincts, respect other people's choices, laugh at retards regardless of pedigree. The kiwifarms way!
Humanity first.
All aliens are bastards.
Literally the only valid position with the arrival of space force. Anyone who says otherwise deserves to be shot into space.
