That blog post is technically correct but not very human. To be curious human to me means questioning other people why they believe what they believe and trying to understand their thinking about it. Of course not always there's good place to have such open minded discussion. If one side, or both sides are only talking and not listening to each other it's pointless monologue and waste of time. It's not helpful to state bunch of facts and let the other person "deal with it". As it's pointed out, often people want to just share something and aren't interested to be lectures or have their opinion changed, that can come later with some introspection, when ready. Personally I wouldn't want to talk to someone who thinks they know it all already and are looking only for arguments.
