Whatever is the case with him, I agree with this post by lee martell in another very recent thread:
The artist should stay away from twitter or social media for a couple of months before he inspires someone to break the law.
The probability of such an "inspiration" doesn't strike me as extremely high, but such a disturbing possibility (that didn't occur at all to my mind before reading that post) is good reason for people, especially the famous and well-liked, to avoid posting certain things online.
What did just occur to my mind is another possibility that disturbs me even more: the idea that a celebrity would post something violent like this with the intention of provoking a follower into what we could call taking action.
I would be happy to kill you personally and watch you bleed out. I won’t do that, because I fear the consequences. But I’d enjoy it, because you mother[f-word] are responsible for torturing my father
Well, I just noticed that not everyone in the world will fear the consequences.
Sleep tight, me!
