If you observe circumstances where whites are forced to rely on race sentiment in order to survive, such as American prisons (where they are a minority, not a majority), they often amount to the most rigid, organized and violent gangs. Where very little room is left for any interaction with anyone "outside of the team"
Sorry, but this is just not true. Regardless of whatever greater point you were trying to make, 'whites' absolutely are NOT "the most rigid, well organized, and violent gangs". In CA, where prison politics demand that people segregate, the Mexicans are overwhelmingly the most militant, well organized, disciplined gangs in CA prisons. Specifically, that would be the Northerners, followed by the Sureno cars.
Outside of CA, where prison politics aren't so serious, whites generally DON'T stick together, even when one of their own is being victimized. If you've ever seen the movie 'Shotcaller', I can tell you that what they showed in the beginning of the movie would never happen in CA - I'm talking about where the main character, a white guy, first enters prison and gets into a fistfight with a black guy on the yard in a CA state penitentiary. That is complete fiction because every single prisoner on that yard knows that if a member of one race is attacked, everyone must jump in and participate. Further, some CA yards have a 'no hands policy', meaning if you have beef with someone, you drop it unless it's worth killing them over. So everyone is strapped. For those reasons, in the real world, individual fights between races are virtually non-existent, other than sanctioned riots/hits. Great care is taken to bring in new guys and school them on the rules. The thinking is that if this new guy fucks up and he is a member of my race, it doesn't matter whether I know him or not, or what car he rolls with. If he does something stupid, and gets himself attacked, every single white guy on that compound must participate unless they want to be booked themselves by their own guys.
Going back to the statement you made, I believe I've corrected you on this before, which I'm pretty sure you ignored. You stated that the "Aryan Brotherhood" has more prison murders than any other gang, and this was your reasoning for saying that whites are the most militant, organized, and violent group in American prison. The only reason the AB had more murders on the books is because the Mexican Mafia were using them as contract killers. Make no mistake about it, the AB is subservient to the Mexican Mafia in CA and a few other Western states.
A large part of the reason why the American white no longer glorifies these elements is because they've been detached from race/class sentiment, molding into one huge group rather than separate ethnic identities, and thus, they no longer identify with those elements, and no longer support them, out of race-based/class-based loyalty.
For blacks, race/class sentiment is still running strong so they are prone to supporting "their own" over anyone of another race, purely based on that sense of loyalty.
Again, from my direct first hand experience, you've got this all backwards.
In prison, whites are the only group that continually espouse racial supremacy. They dedicate their lives to it, rock swastikas, 1488's, etc., and have very sincere beliefs about segregated societies. I'd say about 50% of the peckerwood car (whites) take that shit very seriously. No other group spouts anything even remotely similar beyond just basic prison politics of sticking with your own kind for protection. Don't believe me? Go look at what the Aryan Brotherhood stands for and the imagery they blast all over themselves. Now go look at the big homies in the Mexican Mafia, the Bloods/Crips, MS, Latin Kings, etc. - none of their shit makes race a focal point like the whites make it.
