I supposee how I deal with negative comments depends on their nature. If a comment is just a pointless personal insult, I would probably just report and block them. If it's not a personal insult but they disagree with something I've said, I try to consider what they've said. If it makes me rethink my views, I will say so, but if I still disagree I'm inclined to get into a debate with them. I think that was actually how you and I first came across each other.
Sometimes, if someone has posted a short negative comment, I will try to get a longer reply out of them so I can understand their point better. I try not to view my opinions as fixed, unchanging things. In the quest for personal improvement, I actually want to be challenged a bit. I want some opportunities to rethink my opinions. But only from intelligent people who've actually given it some thought. Some comments aren't worth replying to, because they clearly haven't put much thought into it themselves.
Of course, you're free to disagree with me Susie 🙂
