AOC presumably checked IDs when she worked as a bartender. Was that racist?

Checking the AGE is not racially motivated.

If ID carried the IQ of the person and there were restrictions based on that, you would never have entered.

Nope, there is a legal age limit for the privilege of alcohol.

Mommy and Daddy will explain it to you when you're old enough to drink.

If you feel compelled to "ask" this "question", of course not.  When you reach Grade 6, you will learn in social studies that bartenders have to card anyone who looks like he or she is under 27, at the risk of a high fine or the loss of federal funding for highways.

In 6 or 7 years you will be old enough to drink alcohol.

Perhaps in the butthurt minds of people too young to drink alcohol legally or responsibly.

Only a conservative would think ordering a drink at a bar is the same thing as voting.
