Women usually wont and cant point out that why they find a certain man attractive. To find someone attractive is just a primal response and you cannot always pinpoint what you find in them attractive. 

She wont explain to you that she find his jawline to be chisled, his chin to be strong, his shoulder broad, and a large stature. Most women will just rationalize that why they found a man attractive. They face reprecussion and judgments from others if they openly admits that they find men attractive solely on their superficial aspects. 

We want women to select men who contribute more to society. So more men will be more willing to contribute to society.

Thats why women will hide the actual reason of their attraction and will rationalize into race, status, moral character. 

Or perhaps it could be a fetish for certain race.
