an annoying trope

Once in awhile I read things like this:

“My remarks may seem rude and dismissive, but it’s only because I care so much about philosophy.”

No, if you cared about philosophy you wouldn’t overidentify your own current views with Truth, and you might listen a bit more. What you really “care so much about” is beating other people in arguments. But this is a social desire, not an intellectual one.

They are religious zealots without religion. The psychology is no different.
