I don't think I'm out of touch. Anyone young enough to have the internet, Reddit, and modern social media is very unlikely to be socially conservative over the medium term.
Why? Because young people everywhere (red states and blue states) all like sex (gay and straight), drugs (legal and illegal), and music (country, hiphop, pop). The top 100 list on Apple Music is 50/50 country and poppy hip hop, for example.
The main reason young people affiliate with socially conservative groups (churches, etc.) is to signal membership in a system engineered to get them into a relationship (aka attraction, flirting, sex, etc.). A young male joins the group and immediately gains credibility as being a good person, etc. A young female joins the group and immediately can relax because the males she's meeting are vetted via their membership in the group. A young gay person joins because his/her young gay friends are also members, and they can use the org as cover to spend time together without needing to come out.
Institutions have a label, but their purposes can change very rapidly. Humans are superb at leveraging institutions to achieve their goals.
There are going to be some groups of young people who claim to have highly prejudiced beliefs, etc., but those are fairly common and rarely hold up to scrutiny as the belief holder gets older.
In other words, there is not any sort of youth-oriented grassroots social conservatism in the US. There will always be economic populism, but increasingly there is not a "golden era" in memory for young people to harken back to. Chances are among the stereotypical Trump demographic things were never very cushy economically, and chances are very high that all have had good friends who are African American, latino, hispanic, asian, or any variety of multi-racial backgrounds. Chances are they've had a crush on a multi-racial person and consider the person's humanity far more heavily than their isolated grandparents did (who likely never had many peers or friends from other groups).
