Even half joking about lynching

I think Autismbot was attempting to make commentary on how an enraged group of mostly white folks pinned a "crime" on the one black guy who happened to be walking by and had him demodded and denutted for a 2 year old post that they had previously agreed with.
All while the real criminal, the presumably white mod who made the aphobic commentary, was left unscathed.
That behavior has some parallel with the lynching era.
Autismbot is a simple person, though, so they express themselves through images instead of words.
