That “young liberalism” is simply a false sense of righteousness.
Young liberals derive their sense of “good personhood” from their activist issues, which involve forcing others, through government, to do “the right thing”.
They really recoil when you put in it stark terms - “you’re not a good person, you’re a thief, a cowardly one at that, who uses the guns of government to steal to make you feel good about yourself.”
A young person that is biblically trained won’t fall for that crap.
Yet, you can be Bible at ANY AGE, not just at a young age.
