Is it a problem that some groups have lower IQs than others? For Jason Richwine, it would appear that it depends on whether the group in question is brown or not:
I will leave you with the words of the great man himself:
The bottom line is that a political debate will never be resolved by measuring the IQs of groups on each side of the issue. Even if certain positions tend to be held by less intelligent people, there will usually be plenty of sharp thinkers who take the same side. Rather than focus on the intellectual deficiencies, real or imagined, of certain politicians and their supporters, people should strive to find the best and brightest spokesmen for the opposing side.
