"Its not harassment, its not stalking, its not abuse. Its someone (on both sides) saying something you don't like and/or don't agree with."
Indeed, I agree with that. If protections against curators and commenters are to be built first we need to define what "abuse" is. Protections / filters and the like shouldn't be arbitrary based only on subjective opinions. If people are so thin-skinned they can't handle the criticisms of others perhaps they shouldn't be posting in a public place. Better they see criticism as an opportunity to evaluate their own behavior and position and whether it has positive value.
