I want to believe you, but empirically, this is not true (unless your bar for "plenty" is really low). There are plenty of "based" race-conscious black people, but their "racial consciousness" means that they have pretty much 0 solidarity with people who aren't black. Any type of data you can find, whether it be polling/survey data, election exit polls/voting data, etc, doesn't really support that conclusion.
"Based blacks" aren't going to protect your white business or your white family because they feel some sort of deep devotion to the intellectual ideas behind conservatism, HBD, ethnocentrism, or any other ideology. They will be looking after their own community. Your mixed kids are not going to identify as white or feel solidarity with whites, even if they are 75% white. Most people choose to identify with the most advantaged racial group to which they have a plausible claim, and there are a hell of a lot more gibs and asspats to be had from being any group other than white. "Castizo futurism" is mostly a hardcope.
If we could just temporarily quit the bullshit about labels or ideological self-classification and focus on preparing and organizing as many of your people/your community (whoever or wherever that may be) as possible, then situations like these will go a hell of a lot better. As frustrating as it is to deal with white ancoms, soyboys, and thots, they are still some of the only people in the country who are threatened in the same way by current-year racial politics, and we cannot afford to write all of them off completely. Some of them may very well become uncucked, and even if they don't, unless millions of able-bodied, sane-minded white people start materializing out of thin air across the US, we have little choice but to try to make them see the light. You have to work with what you have, unfortunately.
It may be difficult to impress upon them that all that "ally" shit is never going to make them an honorary negro nor impress Tyrone into not taking their shit when the opportunity presents itself. They may try to resist the realization that a BLM yard sign or a "Coexist" bumper sticker is not going to make criminals spare their home/business like smeared lamb's blood on Passover. But I believe that many are starting to realize these things. And if they don't wake up in time, then we will be fucked no matter what "muh based black man" is saying on Fox.
