In all seriousness, I hope this person will be fine. It is usually detrimental to self preservation, with either active or passive aggression, to openly state what things are. I hope this person can protect himself from any harm of any nature (even harassment).
Incidental, but the cause of Valery Legasov’s death is accepted to be suicide. Whether that is actually what happened I won’t argue for however, it is something I do not know anything about.
I, in just about every case, give no attention to norm-based arguments. We as a species on a whole, proportionally, keep doing foolish shit all the time.
But it was after reading your comment that I noticed there was a time that many Germans were either proponents of or tolerating (not all of them absolutely; there were rebels) some extremely bad things. Some 85 years ago.
