young white people ovewhelmingly back the woke side

This is obviously not true. Even according to NBC, 42% of white Gen Zers and Millennials voted for Trump in 2020 versus 50%/48% for Biden. Given the source, that should be taken as a lower bound.

Any look at the demographics of Antifa and BLM, vs. the demographics of ANY right-wing group show this.

Not true. Look at groups like Patriot Front, National Justice Party, Groyper Army, Generation Identity, Patriotic Alternative, and other European nationalist movements. These are the rightwing counterparts to BLM and Antifa. The Alt-Right as a whole is dominated by under-40s.

they are almost exclusively sexually frustrated males, and "incels" who will not reproduce. 99% of young white women are woke

Both ridiculously untrue statements meant to demoralize.

The truth is that the Right outbreeds the Left, and the further right you go, the higher the birthrate. The main way white Leftism is able to sustain itself multi-generationally is through the education system and media propaganda, and this is now being taken from them as the Right starts to homeschool more and puts an emphasis on teaching their children their true values from birth (something white rightwing parents weren't doing in the past 40 years), and as the Legacy Media continues to go extinct.

As our countries become less white, the persecution of whites will get worse and more whites will be forced to live around non-whites, which will cause the vast majority of whites to be redpilled on race and start advocating for their own interests.
