I think the European gene pool is big enough to allow for adaptations to any conceivable circumstance. Not to mention that single race children don't grow up with identity problems or discrimination from their peers.
But if you married the love of your life, I can't say I can blame you.
I'm guessing she's Asian. Nerds love Asians 
Eh, this is Amerikuh, where you only need Facebook and Jesus to fit in. Additionally most, if not all, Americans I meet are also mutts. Is there a huge difference between:
A) choosing a spouse that complements and strengthens the aspects of yourself that you consider valuable
and
B) choosing a spouse that complement and strengthens the aspect of yourself that you consider valuable AND from a similar genetic stock.
One hopes to make better versions of themselves. I guess if I thought being ERYAN was of value I would see things differently.
It's important to both look through history to find important pieces of knowledge, as well as to realize if alive you are the leading edge on the wave of life and nothing matters unless you decide it matters.
I believe racial pride is a false flag, a time waster value. Better to value creativity, insight, diligence, compassion, wisdom, faithfulness, etc. I think if we are honest with ourselves those are the things we truly admire about the hero, whether we see him in ancient Scandinavia or in the Italian foothillls or the African scrubland or the Mexican flatlands.
If I am wrong about this I would like to know, truth is always worth the price, although that won't stop me from loving my wife.
Shit happens, from time to time, in nature.
But nature doesn't go out of its way to make sure shit happens.
Ah my friend, shit is happening all the time, but rarely on our scale, although that is the scale which with we must deal. Goddamn prepositions.
