No, the parent was simply saying that “trolling” (or, having a bad opinion) doesn’t imply a character flaw, and that we shouldn’t use language that makes that implication, lest we start to think of people who have bad opinions as irredeemable. People can do wrong without being fundamentally bad, broken people.

If we treated, say, driving a car the way people treat Internet discourse, you would be dragged out of your car and stoned to death the first time you cut someone off.

Yes, sure, ignore posts that seem like trolling. Filter or block them, even. But perhaps you could give the people behind those posts a second chance, before writing them off for life for one post.
