Combinations of physical features.
Women have more of a variety b/c of their body shape alone.
In fact, trying to minimize how diverse we are is still a lot of information.
Ethnic groups are largely where we are most diverse, IMO.
Men for example tend to be better than women. We are innately built for speed, strength, intelligence, and problem solving to name a few. We have better pain tolerance than women.
Women are innately better in some areas. They can see more colors and have a better sense of smell.
Most sports are separated b/c of physical, emotional, and intellectual differences and for good reasons.
There is no one way to be a man and no one way to be a woman.
Interests do not make one something. Men can like fashion and women like working with their hands.
Countries used to be great b/c of their uniqueness in ethnicity and culture NOT diversity and inclusion.
There's nothing wrong with say Scottish people being only white Europeans with their culture at the forefront.
You don't get uniqueness by "blending" people from other ethnic groups.
You can simplify that really easily if you kind of put away the Playboy Magazines and try to find a single girlfriend or just limit yourself to one professional career interest. Don't go by color so much for your race guesses or designations. You're making a mistake in race, just follow the Census law. Race is national heritage origin by geology, not by DNA type, DNA research is a biological field that came out of Darwinism. I know you're not going to take my word for this, you'll need to do your own library research on the scientists who have been furthering it since it was pioneered by Darwin's
Origin of Species a book written conjecturing on the coloration of small birds in the 1800s. You're just thinking about the dating game and playing the field by numbers, when you find someone, you'll know it without a bunch of microscope slides and your Kaplow Dice set.
There is a Census Law about race. Separate the Book of Joshua rationally from the Constitution. Census Race is determined from your family name. It's the one you got from your Fater's side of the family. The United States is liberal, but you have to both have a race and know what it is, you also have to be able to prove that you're telling the truth about it (perjury is against the law). Race is family name, and you have to be able to prove that that's your family name, it can't just be from you Dobby nuclear family of origin, you're required to have written documentation of the fact that you were born (Surname). For example, a common name is Klien, which is German. Another really common name is Smith, which is British. You won't have as many race problems in the census if you're already European and speak English, because for example absolutely no one is ever going to try to get you to prove that you're French. French people already know that they're French and can make their own cases in republican courts (besides the United States, France also already has a republic court system, that's just understood). If you are a white person, and you have a race problem, it will be political. Irish Americans have the most political problems with the census, but they also cause the most international political problems diplomatically, it all depends on which way around the Irish are Irish. Russians are the same, but they tend not to immigrate, Russia has its own thing going on, and "Caucasian" means something else entirely in the Census anyway. The people with the most Census problems in terms of race as race per se are the Spanish. Almost no one in the United States is of Spanish descent, most people with Spanish names who speak Spanish are mestizo Indians, but that's because Mexico is of mixed Spanish and Indian race, and once it gets to that level race slides down in the hierarchy of what kind of issues of yours a court is looking at and politics takes over. The red races have the most troubles overall, red people can be anything in reality from Mediterranean westerners to Asian (Korean, Chinese), and the red races are the most likely to cite religion as their distinguishing mark in a family dispute or argument amongst themselves that reaches court.
Legally, your race is your race because of your name. If you have a race issue, you have to be able to prove that your name is your name in court. Red races when in legal race trouble are usually having a religious dispute, white races are usually having a political dispute.
