He doesn't have a monopoly on truth, that sort of presupposes that he was completely right and handled the situation perfectly. Perhaps he'll feel differently when the dust settles as another commenter suggested.
Showing up to a photo shoot in a Goolag shirt also just undermines him as a person. It's totally hyperbolic and ridiculous and will further discredit him in other people's minds because it's an insane overreaction to make that comparison.
You seem to really want him to repent for something. What is it?
I'm pretty sure that being fired - having pitchfork crowds go after you and people who agree - is close enough to being silenced.
