What is the fallacy

We are enrolling our child at a liberal arts classical high-school and a neighboring high-school principal said we just want to drink our chardonnay on the playground. Since I attended the neighboring high-school, I did not learn about logical fallacies and was caught without a response (other than being grateful that my son will be taking 4 years of philosophy outside of this principal's reach). What fallacy does this best fall under? Ad Hominem, Red Herring, or other.....?
Thank you!

It's more of sarcastic quip than a logical fallacy, as there is no error in reasoning. Whether attending a Lacrosse game or even watching an outdoor Shakespeare play imbibing Chardonnay on the playground sounds like a fine way to spend an afternoon or evening.

From the wise-cracking principal it may have a smidgeon of Ad hominem Guilt by Association, as Dr. Bo explains:

Ad Hominem (Guilt by Association)
argumentum ad hominem

(also known as: association fallacy, bad company fallacy, company that you keep fallacy, they’re not like us fallacy, transfer fallacy)

Description: When the source is viewed negatively because of its association with another person or group who is already viewed negatively.

Logical Form:

Person 1 states that Y is true.

Person 2 also states that Y is true, and person 2 is a moron.

Therefore, person 1 must be a moron too.

Example #1:

Delores is a big supporter for equal pay for equal work. This is the same policy that all those extreme feminist groups support. Extremists like Delores should not be taken seriously -- at least politically.

Explanation: Making the assumption that Delores is an extreme feminist simply because she supports a policy that virtually every man and woman also support, is fallacious.
