I think what the sticking point is here is that everyone loves all cookies, so it's really hard to be self critical on this. You anti-semitic peanut butter cookie enthusiasts could never admit the fact that given a Schrödinger's cookie jar full of random cookies, (say chocolate chip, sugar, oatmeal and peanut butter cookies), when that jar is revealed to have 3 cookies left in it, they will all be peanut butter.
Basically, Chocolate Chip Über Alles. And yeah, that's right. Two fucking umlauts!!
