I didn't insult or attack him in any way. I suggested he may have a mental issue and should seek professional help. I'll leave it there and I will refrain from responding to future outbursts in case they are misconstrued.
He has been exhibiting these symptoms for a long time. If I remember correctly, he once posted that he vents on NSC because, otherwise, he might do physical damage. That is very unhealthy imo and he should get help if that is the case.
