What's with the Yang and Vang and their love of inbreeding?
I personally know two Yang man that were shagging their Yang GFs... One of them had 4 children with his gf but was never married - separated now, and the other one is still together with her for the last 5 years - not married either.
I know of a Vang in OR that did the same - dating another Vang girl and had children with her, again... not married.
When I see a female of my clan, even if we're not even close and no matter what she looks like, I only see her like my sisters.
