You think incorrectly. Writing "quite the opposite" after someone's personal experience means literally nothing. At least try and explain why they're wrong instead of writing something vague and ambiguous that on a grammatical and logical level makes no sense whatsoever. Even if you were able to justify why the other person is incorrect, you still can't really exclude and disregard experiences which aren't your own. So "quite the opposite" maybe you think it's an intelligent comment but however you look at it it adds absolutely nothing to the discussion and if anything has the contrary effect in that it creates a bit of confusion. "Literally no way to make it any clearer" I mean honestly it couldn't have been less clear to start with. Hope this helps.
