It doesn't even have to be leftists. Western leftists imply social liberalism, so some being into degenerate stuff is a given. We can look at the "right wing" as well.
Well, I can just drop this one image:
View attachment 5736327
Nicholas J. Fuentes: Watches tranny butt sex porn, paedophile enabler
Groypers: too many paedophiles to name
Ali Alexander: Nonce, sex pest, creeps on young boys (<15)
Dylan Volk: Nonce, 1318.
Latino Zoomer: Caught with CP
Ethan Ralph: Jerked to Soph, lusted after Rittenhouse's 16yo sister, etc.
Flamenco: Lolicon doujins
Torswats: merry band of tranny fucking neonazis, adjacent to freaks in a group called "outer c*nny"
Andrew Tate: scrote, sex trafficker
Or the so called "anti-SJW" types.
Sargon of Akkad: messaging troons
Dax "Juju the Cow" Diddler: tranny simp, sucked off a man
Vedo: self-explanatory
...
Every sphere of grifters are filled with degenerates and creeps.
