You always assume you are right and the other party is wrong, rather than just acknowledging that there can be different approaches to a situation or different viewpoints.
Whenever I say you're wrong about something you are objectively wrong, and I demonstrate it.
You take it upon yourself to prove how wrong the other person's opinion is!
In the other position I would be grateful for the help. This has happened before where someone has shown me something I hadn't seen or considered before, and I was happy to learn from it.
Taking personal offense and getting all upset when someone helps you is a bizarre way to react.
