I mute and block people for a lot of reasons, most of which come back to the fact that if I get triggered it makes me physically ill so I just don& #39;t mess with people who play on the edge.

I periodically try to go through and take people out who I think are unlikely to push my boundaries again but Twitter doesn& #39;t make the lists easy to manage. I& #39;m willing to consider appeals.

But my twitter boundaries don& #39;t have to seem rational to you, they are there for the defense of my sometimes irrational brain which sees danger in odd places and triggers a cascade reaction that activates a completely dysfunctional autonomic stress response.

It& #39;s sort of a miracle that I can function in this environment at all to be honest, I wouldn& #39;t have thought myself capable of doing this in 2016. My weird boundaries are one of the reasons I can, I don& #39;t mean to be unkind.
