I was a Parler registered user and there is no comparison. If you scroll through Facebook you see mostly unflatternig selfies, ads for stupid crap, somebody's random complaint about something you don't care about, a few Trumpies from high school, and maybe 1 comment every 200 meters saying something borderline-violent about Nancy Pelosi etc.

If you scroll through Parler, you barely had to go 1 meter before there's something aggressively violent.
