Ehh could be they are a zoomer from a west coast cohort given how so many peeps I know via my younger cousins are into esoteric non conformist stuff due to how fucked evangelism and other fire brand religions have been. There's also just general "I'm spiritualist" meaning they hope there's a greater meaning to life but aren't sold on all the religions that tell them people in their friend group should go to Hell cuss of X (insert transphobia, homophobia, ethnic persecution, dogmatism).

tldr: lots of zoomers are tired of existing structures of society and so pick the "other" box when people ask "are you religious".
