This is my take on interracial marriages and especially interracial breeding. If you want to call me a racist because it helps you to sleep at night and satisfies your liberal white guilt, go for it. At 63 I have long ago given up caring what others think of me. I speak my mind. If you don't agree with me, well that's your prerogative, move along. If you need, go get some therapy.
Each race is unique, and it is that uniqueness that brings diversity to our planet in myriad different aspects. But when you have interracial breeding that dilutes that uniqueness with half-breeds and with it, it brings other sociological and medical aspects to it as well. I am a retired PhD clinical microbiologist with a Masters in Public Heath so I am more than adequately qualified to bring this point up. Each race and ethic group have genetic diseases unique to that group; SCA (Sickle Cell Anemia), Tay Sachs, Fanconi Syndrome to mention just a few; there are many more. Many are only marginal manageable and some are ultimately fatal. Interbreeding spreads these disease over a much wider demographic so in addition to the sociological aspects, it brings medical aspects to it as well. There are plentiful members of your own race to choose from, can't you find one?
