The Olympics is racist against Arabs, why no heat tolerating events or marrying events?
:/
Edit: I don't think humans with PC levels so high exist such as to deny the effects of genes on performance in various athletic activities, mainly endurance and speed ones. However I believe it is long term climate and food sources as well as breeding habits, as opposed to occupation and politics are the main factors in determining which genes pass.
For instance, compare NK and SK. SK folks are taller and more well built which is soley due to the fact they aren't a starving nation. The Dutch were also notoriously one of the shortest people in Europe at the turn of the 20th century, now look at them.
Edit: I'm Arab...and I'll totally smoke you guys standing in the sun under 50 celsius degrees!
