The leftists are completely invested in Twitter with no fallback. It takes a long time to build up social networks. Their arrogance, pride, and complacency is their end. I currently have four viable accounts (AU, Gab, TS, TG) and a few fallbacks (107, WeGo). Twitter will just be one of many "outlets" that I use. Being deplatformed has also taught me useful lessons about the different audiences on social media and how to pitch my message at the maturity level the followers.
hubris will be their downfall
