Edit: oh, I get it now. Regardless of what one thinks of his argument, it was clear what dmitrygr meant by that, so those personal details didn't add any necessary information. Meanwhile, the damage caused by using someone else's personal details as ammunition is a big deal. We can't allow that to become a thing—nothing would destroy the discourse faster. So, from a moderation point of view: low benefit, high cost, bad idea.
Would you elaborate here a bit please?
dmitrygr said "I wonder if I could sue because I am now being discriminated against?" Can you answer this without considering dmitrygr?
