Sometimes you're right, sometimes they are. Sometimes, as the Rick & Morty quote goes, "Your boos mean nothing, I've seen what makes you cheer."

For sure, but then the followup question is "do I want to spend my time and energy around a bunch of people I think are wrong?'

If they're correct, maybe?

If they're correct, and constantly telling you you're wrong...

… you have an opportunity for self-improvement.

Often times, you comment not to change the mind of the person you're replying to, but to provide a rebuttal for the readers at home. If nobody challenges problematic ideology or corrects misinformation, it can spread like a disease.
