ITT I ask libfags questions

1) Is it wrong to discriminate against certain groups, on the sole basis of skin colour (and not race), by cognitive ability? Please explain why your position position is backed by science. Refrain from answering unless you have a minimal understanding of statistics, please.

Moar questions to follow later, because I feel I'm going to have to deal with a lot of morons with this simple one.

tl;dr You smug retards have, as a group, constantly portrayed yourselves as having science on your side on every single matter of policy. WHERE IS YOUR MARX NOW?
grrr grrr
OP you're asking imprecise questions and then getting angry about it.

Science can't be used to justify racism, is that what you're going for?
