Young people go left in college because they want to change the world, and they think that left-wing social activism is the way to do that. What we need is some sort of compulsory volunteer service: let our young people get rid of their activism bug without making them go Full Degenerate.
In my experience it's more that young people go left because going right means having their frontal lobes scooped out and replaced with a fetid, shredded mess of the stinkiest of ancient propaganda along with a few choice turds from the last century. And now they top it off by stapling a cherry-red hat to their heads afterwards.
