Can someone tell me an example of an Ad Hominem Fallacy from 20 years ago?

An Ad Hominem fallacy is when someone personally attacks you to avert the audience from the real point.

Explanation:

Example:  Person 1 - "We should raise the minimum wage!"

                Person 2 - "Oh please, don't listen to her, she's not even smart

                                   enough to run a business!"

Person 1 attacked Person 2 without even saying why raising the minimum wage is a bad idea. Ad Hominem is when someone insults another person instead of giving reasoning to why their opinion/statement is a bad idea. They try and steer you away from the point so that you agree with them. Maybe Person 1 isn't smart enough to run a business, but maybe she has a good idea in why they should raise the minimum wage.

An ad hominem argument (or argumentum ad hominem in Latin) is used to counter another argument. However, it's based on feelings of prejudice (often irrelevant to the argument), rather than facts, reason, and logic. An ad hominem argument is often a personal attack on someone's character or motive rather than an attempt to address the actual issue at hand.
