That's so unfair. EVERYONE who does something will be criticized by SOMEONE. It's your own fault for only looking at the negative responses and blatantly ignoring the positive. What you're demanding is for NO ONE to EVER say a SINGLE bad thing about ANYONE ever and that's just obscene.
It is not unfair for creators to ask not to be abused online.
It is unfair to demand that creators listen to and engage with their audience while taking their abuse in stride.
There's a clear distinction between genuinely constructive feedback (even if it comes from a place of passion) and vitriolic abuse. This should not be a radical or crazy idea.
