It’s another example of how there is no satisfying the perpetually outraged. No apology is good enough, no effort to educate is good enough. You’re dealing with a mix of misanthropes, trolls, and people who are angry about their own lives or some other internal issue. So they redirect it at others in order to comfort themselves.
You’re only wasting your time chasing the approval of people who will always find another reason to be angry and dismissive of anyone’s efforts to learn and improve.
