Not surprising since young Republicans tend to be more radical than other age brackets, mainly because they grew up in the age of MAGA where hatred and bigotry became publicly accepted and encouraged by the right wing.
They're probably more racist than most older Republicans too. Some of the racist stuff I heard from old conservatives 20 years ago (people who would be well over 100 now if they were alive) doesn't even compare to the Nazi-esque school shooter language I hear from Joe Rogan fans under 35 today.
Young people just seem to be very radical these days, left or right. Just look at the borderline pro-Hamas positions of a lot of the young left. Perhaps the impact of growing up in the social media age has fried their brains? Hopefully the 50-60% of young people who are not yet politically active will be more moderate once they start voting.
