/sci/ - Science & Math

Why is /sci/ so scared to discuss race and IQ? I've brought it up in a couple threads and been told to go back to /pol/ (which I don't even use).
Shouldn't we be willing to discuss things that make us uncomfortable? Hell, we tell people that there is no evidence for a God and that it's very likely they just decompose after death, all the injustices of the world and their lives not to be redeemed or balanced out in some kind of afterlife. Frankly, the idea that different races have different IQ averages doesn't even seem so cruel in comparison.
Let's have a POLITE, honest discussion please.

Who inspires you?

The way Neil Degrasse Tyson inspires me is how I want to inspire someone one day.
