Yep. Parler is one of those social sites that pitches itself as a champion of free speech, like Gab or 8chan. But like those sites, it's turning into a haven for people who got banned from the mainstream social networks for falsehoods, hate speech and threats of violence.
There's a certain irony to those sites. Without adequate moderation, they become so toxic that they quickly devolve into echo chambers for the small group of people who tolerate or participate in that toxicity. They render themselves more irrelevant than if they'd just abided by the rules on Facebook or Twitter.
