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.
