You do understand that if their side does the same, you won't have any kind of moral high ground to stand on because you have already condoned stooping to their level?
I'm not sure how much that would mean swinging from the rafters of [insert intolerant country]. The white supremacists will maybe lose their jobs or reputation, but the consequences could be much more dire in retaliation.
something something, "If we extend unlimited tolerance even to those who are intolerant, if we are not prepared to defend a tolerant society against the onslaught of the intolerant, then the tolerant will be destroyed, and tolerance with them," something something
You're exaggerating. Yes, it gives up the "doxxing not OK", but there will often remain a large moral difference between "Alice was accurately doxxed as KKK/Nazi" versus "Bob was accurately doxxed as $X."
There are very few $X which are both worse, plausible, and "the other side."
We also need to ask who is going to care or be convinced. Orwell's The Party does not care about ethical or moral consistency, only power.
Weird moral equivocation. Nazis declare themselves enemies of mankind. They otherise themselves with their beliefs. It should be legal to stone them in the streets as non humans.
If "Their Side" did the same to innocent people who hadn't declared they are everyone's enemies its a completely different scenario.
