This surprised me (too) at first blush, but after thinking about it for a while....
When I examine the prevailing attitudes of enlistment age kids these days I see a bunch of political agnostics who have received a heavy indoctrination of insanity (AKA liberalism). Few of them have held more than a menial-labor job (responsibility), few are married (commitment), and very few own anything of substance like a house & mortgage (financial discipline). Selfish, self-indulgent, narcissistic people are the breeding ground for liberalism. Life experience, self-examination, and acceptance of responsibility is the soil upon which conservatism grows and prospers.
“If you're not a liberal at twenty you have no heart, if you're not a conservative at forty you have no brain.”
It didn't apply to me but I've seen it applicable to more than a few so I'm gonna give it some credence.
