I think frequency will be hard to prove right now, but when you have things like this, they are completely justified. If it walks like a duck and quacks like a duck, it's probably a duck.:
"Parler, the "free speech" social network, reportedly removed a post by Lin Wood, in which the pro-Trump lawyer threatened violence against Vice President Mike Pence.
"Get the firing squads ready. Pence goes FIRST," wrote Wood, according to Mediate. "
I agree frequency is hard to prove but I think its important. If Twitter has a similar or higher frequency then they would also be guilty of consistently inciting violence as well and any person who is consistent should be trying to get Twitter pull off app stores.
I can easily find tweets that are violent that stay up for weeks after being reported. It feels like Twitter is being held to a different standard than Parler and that is my issue.
