What I think is especially unhelpful is people who have not read enough theory to understand what they are talking about (let alone considered it in the context it was written), but they are passionate about an issue so they try to debate people using the logic of that theory and they end up just making the theory seem like nonsense because they didn’t understand it.

This is very common, well said! And thanks for the complement. My goal is mostly to make sure people unify theory and practice, theory is a guide to action.
