No protected speech "needs to stop". You're allowed to have a different opinion. You're a total jerk to say that other people can't express theirs.
(An even bigger jerk than trash-talking bitcoiners, who afaik aren't saying "ethereum users need to stop".)
Im not saying people shouldnt be free to say whatever they want, but if it is malicious I believe we as a community need to downvote and repress opinions that add zero value to anyone. There is no value added when people run in and say "Fuck bitcoin, ethereum is #1" and vice versa. Having an opposite opinion that portrayed in a civil way should in no way be downvoted or suppressed.
