With respect, that is simply not so. NO ONE has been banned for 'standing up for their convictions'. They have been banned because when they continually failed to convince others of the correctness of their convictions, they resorted to ridicule, abuse, deceit, sophistry and subterfuge in attempts to bully, intimidate and otherwise impose their 'convictions'.
They were allowed great latitude and were given repeated warnings to cease the LYING and ABUSE, and when it because clear to JR that they had no intention of heeding those warnings, he had to act, and quite properly so.
No has been banned for their convictions; they were banned for their dishonesty and incivility in promoting them.
Incivility. Hmmm.
Is that sort of like telling someone, "Up yours, asswipe," when all they've done is lay out a case for their candidate?
