After years of social media use I've come to the conclusion that bubbles are good, actually. In no other aspect of our lives are we expected to invite assholes over on the theory that they might be convinced to adopt our views. I didn't sign up because I wanted another source of stress in my life.
I used to be pretty slow with the block button, largely because I don't want to curtail my own reach, but recently I've been getting enough hostile QTs that put my words in front of various TESCREAL cult-members and the responses are getting tedious. So, blocking it is!
