By "way over the top" I meant that your analogy was excessive and distracting. This should not be hard to understand. As everyone knows, there's a vast history of people arguing ad Hitlerum in internet flamewars. It was already a cliché decades ago—in fact it is the most notorious internet cliché of all time. When invoked in the context of contemporary political debates, it's pure flamebait. That's against the site guidelines because it leads to flamewars, which we don't want here.

Not only that but your comment contained other flamebait besides the Holocaust invocation. "Don't worry, there's plenty of time yet" and "So excuse me for not being impressed by your" were obvious provocations. That's not "a perfectly civil manner".

"Factual" is a red herring - there are infinitely many facts. They don't select themselves; humans do that. https://hn.algolia.com/?dateRange=all&page=0&prefix=false&qu...
