Another important point --

We shouldn't use the word "racism" because what does that word even mean?

It's useless to utter the word unless you're going to take the time to define it. It's a buzzword, a loaded term that the Media has crafted. It's far too malleable and nebulous to be useful.

I would refuse to answer a question like "Are you racist?" because I have no idea what they mean by that.

If they mean "Are you proud to be white?" then yes. If they mean "Do you want your children to marry other whites?" then yes. If they mean, "Do you especially enjoy the company of your own race?" then yes. If they mean "Do you prefer living in societies built by whites/your own race?" then yes.
But I strongly disagree that ANY of those are bad things.

If they mean "Do you hate this or that people group?" then no. If they mean, "Do you advocate and/or practice various rudeness, crimes, harassment, etc. against other races" then no.
Et cetera.

I think we should be kind to black people, they are God's children too. But we must be realistic (for example, being cautious in various situations -- not placing yourself in dangerous situations for the sake of woke delusions)
And I would still prefer that all of my children marry within their race (assuming they marry). That is very politically incorrect to say in these woke, Communist times, but I don't care. It's natural and human to prefer your own kind. Water seeks its own level. Birds of a feather flock together.
Miscegenation brings a set of problems and challenges I have no experience dealing with, so I would rather not have to deal with them.
I think a lot of people vastly UNDERestimate just how different many races are -- and about some very fundamental things. Marriage is already challenging enough; why dial up the difficulty to "nightmare" mode?

If you want to foster some kind of harmonious one world melting pot -- I would advise just make lots of friends, business associates, and acquaintances of various races. But for intimate, permanent relations like marriage -- I'd say stick to your own culture and/or race, for best results.

Of course not all races are equal, and not all races are equally different from each other. Some "combos" work better than others. It's a combination of culture, and physical/temperament differences. There are physical differences between the races, which goes beyond upbringing or culture. But culture is probably the #1 biggest factor.
But you have to realize there are issues with children of mixed-race marriages -- they have a hard time identifying with either parent's race. Again, not something my kids have had to deal with, something I've never dealt with myself. So I'd prefer to keep it that way.

If you take the word/slang, "Nigger", and subtract a letter "g", you have Niger. Niger is a country in Africa ! 😃
