I don't.
I think many people think 17 is the same as 18 and maybe 16 too.
AoC below 16 is a harder sell but still doable to at least 14.
If leftists were serious, they could easily lower AoC to 14-16 with little pushback, far less then they received for transgenderism.
White Nationalism or Nationalism in general in incredibly unpopular because most whites know good non whites and bad whites, compartmentalize the racial problems such as white flight and think we can ignore or overcome any racial tension.
Most Whites believe that rejecting people because of their race is wrong and America should be a nation of immigrants where everyone is given an opportunity to succeed. (Ronald Reagan vision)
Most White Americans don't care if they become a minority, don't care if their grandkids are mixed race, think crime and intelligence is cultural and think America will remain the same nation when whites are replaced.
Most White Americans are completely on board with population replacement and white genocide, they just want leftists to stop being mean to Whites, maybe not teach CRT?
Even the Whites who claim to support borders and think open borders is insane still want massive legal immigration to the point that Whites are replaced.
Most Whites have completely rejected biology and eugenics in favor of not hurting people's feelings.
Anti racism is the most successful propaganda campaign in recent human history.
These people are so weak that they can't even stop affirmative action and they're starting to lose on the reparations argument.
"Haha left is soo crazy" and even "left is anti white" is an easy sell but, "becoming a minority is a mistake" is an incredibly difficult sell. "well I have non white friends and everything is okay so who cares if we become a minority?" or "only leftists care about race. You must be a leftist." I think this convo shows the power of echo chambers and bubbles. Your perspective is inverted from reality.
@Pee Cola If I wanted to grift easily. Grifting AoC as a leftist would be the easiest grift. I bet a large percentage of them would support it and there would be no risk of deplatforming. WN despite being milquetoast online is incredibly unpopular IRL.
