Earlier quoted context omitted.
It's rarely/ever paid off to engage with you on these issues, but if you genuinely do care, I have a 10 year history in which some of my comments have been killed, and in the majority of those comments it's been because of the very existence of disagreement, not because of the nature of how the disagreement was playing out.
It's impossible to say for sure without links, but those comments were probably killed either by user flags or by software, rather than by moderators. We don't typically kill comments outright unless we're banning the account.
This is entirely false, and I'm not sure why you're saying it. I literally have emails from you saying exactly the opposite.
