As far as the high profile sites are concerned, civil discussion is dead. Twitter is full of hatred. People who disagree with you will threaten you and try to publicly shame you. Someone takes something out of context, then shares it with hundreds/thousands of other like-minded people and attempts to get them all to target you. Facebook is full of ignorance. Doesn't matter what you say, some ill informed person will speak over you and refute your points. FB is absolutely the worst for this. The public posts about controversial issues is loaded with ignorant people spouting nonsense over others. Reddit is full of downvote and report abusers. If someone disagrees with you, they and their friends will downvote your comment until it collapses due to the negative vote threshold. The more extremist ones will report every single thing you say and attempt to get you banned. These sites also have no recourse for abuse. Once you are banned, it is next to impossible to get it overturned.
