You're pretty quick to forget the Autonomous zone in Seattle where people died, or the continuous destruction in Portland over the last few months.

Either Parler and Twitter are both dangerous or neither of them are.

There can be a difference in degree, it's not a binary option.

Personally I think both are dangerous, but thanks to audience self-selection and rules of the platforms, Parler is more dangerous of the two.

Correct, You obviously forgot the last 8 months where multiple people were killed, federal and private buildings were lit on fire, politicians were assaulted and they setup multiple "autonomous" zones. Perhaps I missed the latest phase of word games where the word 'milkshakes' encapsulates this sort of behavior?

25 people died in their riots last year.
