Twitter's leadership is a bunch of cowards who are only now taking the smallest steps to do something about Trump's lies and demagoguery. They should have banned him years ago.
I stopped using Twitter on January 20th, 2017. I had been a user since they started, but I went through and programatically deleted every tweet, like, follower, etc. I now just have my name and I never use the site. I wish more people would do the same. Don't delete your account, just stop using it.
If Twitter had just held everyone on their platform to the same standards, I would be somewhat accepting of them as a neutral platform for free speech. But they decided to ignore the threats, lies, bullying, name calling, racism, sexism and more coming from not just Trump, but all of his followers. So they can go to hell for all I care now.
