Blacks do not come in "extremely super smart" just "above average" at best, as average is defined by the mean intelligence of the white or Asian population.
Well, seeing as black people can't be "extremely super smart" and you are against mixed race relationships because the children are "bastard children", and as I recall you've pretty much stated that the genetics of black people are inferior in the grounds of intelligence, I would like you to explain something to me. A few months ago a two year old child, Elise Tan Roberts, was admitted to MENSA as its youngest member with a genius level IQ of 156. That's the top .2 percent, so I think that qualifies as "extremely super smart".
Here's the thing - her father is a black man. As far as I know he isn't a genius, and neither is her mother. Since she's a girl, she has her father's X chromosome. Some rather decent science has shown that the X chromosome is linked to intelligence, which is why we see wider diversity in men's intelligence compared to women. Having two sort of averages things out. So, shouldn't this mixed race child not be a genius since she's the result of a mixed race relationship involving a black man? Being the bastard child of a mongrel relationship, as you so non-hatefully put it, wouldn't his black genes drag her down?
