A dilemma about these blacks

[Tony]

I was surfin SSC and found this thread , one posted these samples as the typical American faces , for joke ok but when I looked at them I could notice one standing out , the last on the right upper row , while I found the others scaring and very different from me I instead find this one instinctvely like not an enemy but someone you can trust or even , hipothetically speaking , befriend.
And at the same time I find the first four upper row and the first one left below as the ugliest sons of a bitch , especially the number 6 , even if I don't know him and he didn't me nothing I feel like I hate him , kill him and wish he die asap.
Why these different feelings?
What are they dictated by?

nvm, Not sure why you trust that guy more...

If anything, the one in the front row center is probably the whitest: Jason Kidd, who had a light skinned black father and Irish-American mother (yep, the Irish girl again).

I don't know why too and cannot explain to myself , it's not rational , it's based on pure instinct , even if he looks a badass I'm not scared at all by him while about #6 I very feel like he's a criminal or a bandit , I wish he disappered from the earth.
It's not about skintone otherwise I would have had to trust more of all #5 and then #7 , it must be something else I can't detect right now , I'm gonna wait for Agrippa hoping he will have the right answer.

I think that your brain is determining relative genetic distance from yourself.

Fixed.
