Rebecca Solnit: How to Comment on Social Media:
Also you have the right to check their papers, as in to demand they prove to you their commitments and beliefs, and their unwillingness to do so on demand is a sign of culpability too. Have they properly condemned the recent something or other? It is not your job to find proof; it is this complete stranger’s obligation to offer it up, and there is no reason they would not if they were not guilty as charged. Condemn them for insufficient condemnation issuance.
This is amazingly funny, but you’re a better person than I if you don’t wince, too.
