I have a girlfriend from Thailand, who I love. I just cant see myself ever having kids with her.Is this racist?

I am Scottish through and through. When I look at my child I want to see a little scottish highlander that looks a bit like my dad and my grandad and my great grandad. I want to keep the bloodline pure (wtf). Jesus, Im sounding like some kind of f*cking vampire here, but if my son looks chinese a little bit of me will always be disappointed. I dont know if this is actually racist because this is the way genuinely feel. What do you think?
