This is a very odd response. It implies that how strongly you feel about something is measurable by the anger you feel towards those who feel otherwise.

I am not "cool" with lackadaisical responses to COVID, no. And I've said so when opportunity to do so has arisen.

But I have not said so with venom in my voice or hatred for my fellow human. The old adage, "You catch more flies with honey than with vinegar" applies. If you want to bring people to your point of view, you won't do so by insulting their intelligence or disparaging their character.

But, you do you.
