My youngest daughter and many of her friends are Straight Edge, but not vegan. Most are really into music, and seem to be working through idealism but disenchantment with the way society works, hence the anger in that comes out in the music. They’re not drinking the Kool-aid. They seem to be polar opposite of sorority/fraternity kids. Most have a really good personal value system, and aren’t fake. There’s no drugs going on, none of them smoke, drinking is usually beer only, and cheap beer at that. Most shop at the goodwill, aren’t into materialism, play a lot of original music or go to local shows, hang out in coffee shops, and can fix things. A lot are content to work low wage jobs and make enough money just to get by.
Several churches have sprung up in our area that seem to attract aging Straight Edgers. They are a community of artists and back to the land types with an urban community improvement focus. Example: they had a fall festival for the neighborhood the church is in, and offered free food, free family photo portraits, art activities for kids, brought in a petting zoo for city kids, sold low cost original art.
