What’s up with all these far right figures converting to Catholicism?

Just saw a blurb on my Reddit feed about a former child actor posting some awful stuff on Twitter. Turns out he’s an extremist who converted to Catholicism a few years ago. That led me down a rabbit hole of Googling different right wing conservative writers and politicians who’ve converted over the past few years and have embraced ultra-traditional Catholic views, including JD Vance. I’m not Catholic, but have lots of friends and family who are. They still go to mass and send their kids to Catholic schools, but it seems like a far cry from Rod Dreher and others like him practice and believe. Does anyone here have any thoughts on or particular knowledge about this?
