Youths lean left because progressives are so much louder than the right. So the young, unacquainted with the lie-destroying lessons of experience, arrive at early adulthood having heard only one side of the story. The right makes little political noise, because the right is too busy being good parents, paying taxes and not sucking at life.
Politics suck. Politics are a wet blanket to the spirit. Polotics should be avoided if possible. The problem is that the enforcement of radical progressivism is now the central goal of all important institutions in western civilization. So non-compromised soldiers of the right would do well to stand up, speak their peace and be counted if only to mitigate the terrible consequences that our current situation has on our young ones.
