If this helps, I for one do tend to give a lot of thought to what people are writing or replying to me - maybe way too much sometimes to the point where it can affect my mood, a lot. I don't really draw that line between "online conversation" and "real conversation", which a lot of youngens seem to do nowadays. I didn't grow up with the noise-pollution internet 2.0 for and from the masses, maybe that is why. For me it is as real a conversation as any with a person I don't personally know; if someone in real would reply to me like that, I would feel just as bad or offended or I would just as much re-research my point if I was wrong.

Otherwise what's the whole point of "social media" if all you are doing is stroking your own ego and not learning any thing?
