I would feel strong negative emotions for sure. That would be fine. I want to feel emotions and be challenged.

I would be extremely motivated to prove Linus wrong. If I would realize I was wrong, I would lick my wounds and be hurt. The hurt felt would be related to the amount of work and effort I would have invested. I would not claim that Linus is responsible for my emotional state. I was challenged and I lost.

Identifying with your ideas is fine in moderation but taking lasting personal offense is when your ideas forcefully rejected is madness.
