I find this article amusing. I think it puts forward something interesting but frame it completely incorrectly.
The author doesn't actually want to lose debates even if it doesn't seem to realise it. He doesn't want to have debates at all. He just wants to have conversations with people and less preconceptions. That's something I'm completely in line with. I believe we suffer as a society from a collective excess of opinions.
The funny thing is that even when he tries to describe is prejudice in an unprejudiced way, he horribly fails at it.
