Watching self-discovery instead of being hit over the head with it is always fascinating.
Every 20 something thinks with absolute certainty that their political views wont change with age. And that it's only a matter of time until the rest of the world catches up to their 'correct' views.
You think 50 years ago they ever thought there would be gay conservatives? Conservatives that would support gay marriage? So they aren't socially conservative, at least not completely.
On the other side, I am not sure how to explain this properly but I find I am less liberal with age but even more progressive.
Personally, I've actually become more culturally liberal the further I get out of university. College liberals are awful and horrendously stupid to boot, but seeing people who've left their parents' support and still manage to hold liberal positions drives me towards that position.
Kind of like how conservatives tend to oppose gay marriage right up until meeting the average actual gay couple, and realizing that, hold on, those "godless liberals" are just like us "normal, decent folk"!
And in their defense, conservatives have been getting steadily more "liberal" every generation. Even my grandmother doesn't hate other races and ethnicities from us the way her grandmother did. Grandma even crossed one of her our people's real lines by accepting my Christian girlfriend.
