There also exist plenty of screenshots of Twitter and Facebook posts advocating violence and racial supremacy.

Of course. I was just pointing out that it's easy to expand your knowledge beyond first hand experience.

Of course they are.

They are easy to find for every platform.

It’s doublespeak to say “I saw no calls for violence when I was on platform” and then to say “of course there was calls for violence on the platform, they are on every platform”.

Which is it? Facebook optimizes for engagement.. Parler optimizes for free speech.

Why did Parler optimize for free speech? Is it because some of the members were being banned from the other platforms for extremism?

Did Parler gain network effect because of those certain members moving over to the platform?

You have to think deeper about the whys here.

I’m certain they existed; I just didn’t see any, in a month or so of very active trawling of Parler.

So, in my experience, Parler’s primary purpose was unlikely the planning of evil.
