College age people aren't that moldable. They are more interested in rebelling against cultural norms, sticking it to 'the man'. When the cultural norms are dominated conservative thought, you get the flower children of the 60s. Now with leftwing thought becoming dominate, kids that rebel, kids that want to be a part of the 'counter-culture' have to move right.With the far left, it isn't about Rittenhouse. They couldn't care less about those who were killed. It is about controlling the narrative in any situation and spreading the socialist lies to influence the masses. College age people are easily molded into accepting these lies that on the surface look good. Of course there is the quote that isn't clearly attributed to anyone, "If you aren't a liberal at 20, you have no heart and if you aren't conservative by 40, you have no brain!"
When 'the man' is a virtue signaling, non-binary, pansexual, screaming about the horrors of climate change, you get plenty of young people attending Trump rallies.
