NOT ALL DESCRIPTORS ARE LABELS

The term "Millenial" is not a label in the same sense as "Liberal" or "Atheist" are labels. It's a category; it's an age group. You can be born in any year and choose your political leaning and describe it as"liberal" or any other number of ways. You can believe in one god, zero gods, or a multitude of gods, at any age, and thus call yourself an "agnostic atheist" or whatever you want.

But you can't be a young baby boomer, and you can't choose to describe yourself as a "Millenial" if you're 70 years old.

So saying "As a millenial, I don't like labels" does not make you look like a retard.

Creating endless memes in bad faith about that phrase does.
