Mixing race is bad and degenerate ,kids from interracial couples have a lower iq,teeth problem, their facial structure isn't symmetrical (that's why they appear very wierd for normal people) they will have identity crises when they grow up and gonna be the Reserve soldiers of the (((cosmopolitan golbalists))) to destroy homogeneous societies (mixed-race shits tend to support more faggotry and other kikes' propaganda , rapugees etc)
Different races have different skulls,if 2 races mix together they aren't gonna give birth to a healthy kid,
how about a challenge, name me any genius/scientist/someone who did something to humanity who was from an interracial relationship
