This is feels too much like doxxing for me. The man is complete scum, but he deserves his online privacy until proven of doing something illegal. donating money to a website isn't illegal, and neither is stating your opinion. Catch him with child porn, or actively promoting hate speech (Illegal in CAN where I'm from, not sure about here).
I think you have a question wrongly phrased there. I think the better way to ask the question is "At what point is it okay for a journalist to publish a person's Identity without their permission?", and I think that that's a very important question too. If Ms. Beirich had evidence of Mr. Holthoff actively promoting Racism in his classroom, or something illegal, and had informed the authorities (or his school system) and nothing was being done, then I would be okay with people naming names. As it stands right now, and with the information we have, Mr. Holthoff has not broken the law, so there is no reason I should know his name. Again I have to go to the comparison to cases of doxxing on the internet, where people find something someone says or does disagreeable, and go out of their way to make sure everyone on the internet knows exactly who they are, where they live, where they work, etc, so that they can be harassed. Just because we disagree with these people, or how they view the world, does not mean that we have the right to shame them for their opinion or how they live their life, no matter how distasteful we find it.
Not illegal in the states, unless it's something intended to encourage people to do something illegal right that moment and likely to work. We allow Klan rallies, but not saying "let's go lynch that guy."actively promoting hate speech (Illegal in CAN where I'm from, not sure about here).
In Canada, hate speech is anything "intended or likely to circulate extreme feelings of opprobrium and enmity against a racial or religious group". The landmark case being Her Majesty The Queen V. James Keegstra, who interestingly, was also a public school teacher:In 1984, he was charged under section 281.2(2) of the Criminal Code [now 319(2)] ("Every one who, by communicating statements, other than in private conversation, wilfully promotes hatred against any identifiable group")[1] for "promoting hatred against an identifiable group by communicating anti-semitic statements to his students". During class, he would describe Jews as a people of profound evil who had "created the Holocaust to gain sympathy." He also tested his students in exams on his theories and opinion of Jews.
