Parler is seeing a big influx right now and in particular at Twitter's expense. I don't know of a YouTube equivalent that's got any real traction ATM but it's surely coming.Someone from the right just needs to create a site for free speech, where people aren't going to be banned for expressing their feelings. If it became popular and every right winger used it, not only would it hurt the likes of Twitter and YouTube, which have a massive left wing bias as policy, it'd just infuriate the left that there's an outlet which spreads the thing they most despise; free speech.
The idea of social media sites bringing everyone together has, unfortunately, failed. It's time for a clean break, the left to still hammer the Twitter echo chamber, and for the right to have their own platform to discuss ideas.
