Knee jerk liberal arguements: Installment Three

Standard knee jerk liberal argument #3: "Not (blank) enough."

In this argument form, a knee jerk liberal denounces a mainstream person or object because it somehow lacks the true essence of a marginalized group or thing.

Brokeback Mountain? Not gay enough.

Barack Obama? Not black enough.

Arguments like this are a symptom of a larger issue: the automatic (dare I say knee-jerk) rejection of the mainstream. They also imply that single persons or works of art must be perfectly indicative of a larger population. Because Barack isn't like most black people on TV, he is therefore "not black enough." Shouldn't he have known to fashion his personality to mirror an entire heterogeneous minority???
