First of all, I'm not a /pol/tard or white supremacist. Hell, I'm not even white, I'm Mexican. I don't consider myself as a racist person because this shit it's always related to some conspiracy theory shit, like > da jooz and so on.

However, since my country it's full of different ethnicities and indigenous tribes, sometimes it's hard to me to believe that they aren't races at all. Not because they are "savage" or bad, because sometimes they are completely different to us, in terms of physical appearance, cultural differences, etc.

Another thing is pic related, the author doesn't imply that races exist but it defends the idea that intelligence is mostly related to genetic factors, and environmental factors don't have much weight. So, why do races don't exist? Honestly, I don't know much about biology, so I'm partially ignorant about this topic.

Sorry for my poor English, btw.
