Does /b/ have mongoloid ear lobes or proper white ear lobes

I've never cared about it consciously but eventually I began to notice that there are people that have ears that grow right out of their head with no earlobes.
Since then I could not unsee it. Atrached earlobes give me the ick and my granma said you can't trust these people.
Whats your opinion on that matter? are there races with higher or lower percentages of attached or detached earlobe?
