In jb55's case I talk shit about him for being an Apple glowie, but in the past I did it with more respectful words, because I respected him.

Some of them are people I've actually disrespected, some of them are people I've only been nice to. They mute me because they're sick and can't handle seeing certain delusions challenged in a serious way.

I also suspect there's gotta be some malware that mutes me on people's behalf undetected via compromised keys or apps.
