When a white person mixes with a black the baby's IQ drops significantly from what it would have been otherwise. Biological fact. The average IQ of non-whites is on average 20 to 30 points lower than the average white. Yes it does matter. Playing basketball foesn't build space ships. THE MOST IMPORTANT FACTOR IN RACE IS INTELLIGENCE.

Without white men the rest of the browns would quickly revert back to tribal societies. This is an incontrovertible fact. For the sake of the entire population the white race needs to be preserved.
