Everyone is equally "loud" on Twitter. And you're not allowed to hurl racist abuse at speakers in public, either.
(You know, if there was some kind of agreement that tweets containing only the wood "boooo" were definitely not harrasment, that might actually be an improvement on the current situation. It's the "I'm going to find you and murder you" and "incoherent string of racial slurs with frog emoji" that are the problem.
I don't know where you are from but in the US you most certainly are allowed to hurl racist slurs at speakers in public. It's up to the rest of the crowd to then shout back and speak truth back to the racist. As long as the racist is not shouting how to kill said public speaker or speaking libel, he's legally allowed.
Granted, we get into international situations and Twitter is private anyway. Just noting that "allowed" is not as black/white as you paint it and I wouldn't have it any other way. Would rather have minority groups be able to display their true selves to be judged than silenced.
On the "booo" comment though, you may have a helping idea. Maybe instead of a knee-jerk reaction to comment some obscenities, others would just be willing to -1 / boo / disagree in some way. One-click would be used over typing out the comment.
Don't you think services should generally strive for a higher behavior standard than the US penal code? Should anything that doesn't land you in jail be accepted?
