have you read his tweets? this has nothing to do with free speech. You are free to post as much conservative philosophy on twitter as you want, but you can't post blatantly treasonous and violence-inciting falsehoods. Twitter allows the accounts of 99% of republicans to go completely uncensored. This is not about censoring the right, it's about protecting our republic and way of life from a violent demagogue. We don't want another Mussolini on our hands.
For the record, I lean conservative/libertarian on most issues
