From @dang's other reply[0], you have nothing to apologize for. Your insult might've been a bit childish, but it's only being used as a flimsy excuse to silence "mob dynamics" (popular opinion going in a way that isn't approved).

HN has had dozens if not hundreds of threads about this topic over the years, including a megathread a few days ago: https://news.ycombinator.com/item?id=38795308, and this megathread before that: https://news.ycombinator.com/item?id=38531104. No one is being "silenced". It's one of the most discussed topics on the site!

It's just standard moderation not to allow a comment beginning "so-and-so is frankly a moron" at the top of a HN thread.
