Good point, and I can't always be right, I know. If I suspect someone is a real person I almost always treat them with respect because, as you say, we need to mend the fabric.
I think I'm doing more good than harm because even if I get it wrong, I'm highlighting the issue. If someone sees me call out suspected disinformation, maybe they'll think more critically.
At the end of the day, I dislike doing it, but I think its the right thing to do.
