You are making a whole bunch of assumptions about my position here. That any deviation from a pure principle is going to become permanent, or that I'd support it becoming permanent. And that is just not what I'm arguing for.

As I said elsewhere, it's not that it's intended to be permanent. It's that temporary solutions often entrench themselves as stubbornly as permanent ones. But I'm done with this argument as a whole. I think we started poorly but ended better, but the whole subject exhausts me. Please just keep in mind that these exclusionary behaviors, in addition to the principles mentioned, create no end of trouble simply by their very existence with regards to the identity and belonging of mixed-race individuals.
