Ad hominem

From The Wikipedia

An ad hominem argument... is a logical fallacy that involves replying
to an argument or assertion by addressing the person presenting the
argument or assertion rather than the argument itself.

...

As a technique of rhetoric, it is powerful and used often, despite its
lack of subtlety.

The Pledge

I just heard that the Pledge of Allegiance didn't have the words
"under god" until 1954. Eisenhower signed the change as
another means of differentiating the US from the (atheist) USSR.
