Ah, so. Is there a taboo on introspection in CFI culture?
This is the modern version of the Inquisition. No more torture or banishment, just ridicule. You don't actually have an argument, you just claim that the other guy doesn't and offer that as proof of... something... we don't really know. If you are hosting guests or in a public situation where enough people agree with you, it can be effective in at least silencing your opposition. In a discussion group with intelligent people, it's just silly.
