I read some of the thread, yet will simply comment from my own world so that I can simply answer the ?.
My mother was pure german from a high german back ground. She married my dad who was pure Irish.
Which makes me Irish/German.
I married my wife who is Welsh/Gaelic.
We have 8 kids and soon to be 9 come Jan.
My answer to the ? of the thread is I really could care less about what race or color my wife is. I did not fall in love with her because of her skin color but for who she is as a whole. If anyone were to come to me to sugges that I should have stayed with a Irish or German person I would have to pick them up turn them upsidedown and shake them a few times to knock their brain free. I would never think to tell someone else what they can or can not do with their life. I might offer a suggestion or advice but never would I think or expect that I have the space, place or grace to try to have someone live according to the confines of my thoughts.
When it all comes down to it, it must be about being with the person you love, not about keeping racial purity. I think that racial purist actually end up being somewhat retarded in a true sense of the word because of limiting the gene pool from which they draw their spouse.
