Resort is had to ridicule only when reason is against us.
—Thomas Jefferson

When incredulity becomes a faith, it is less rational than a religion.

—Jules de Goncourt

Two other common fallacies you will often encounter are argument from ridicule and argument from incredulity.

Argument from ridicule

The argument from ridicule fallacy occurs when instead of refuting an argument, a person will ridicule the argument as if not worthy of consideration.

Example:

Person1: Believing in things you can't justify is illogical. Philosophical atheists cannot justify their belief that God is imaginary. Therefore atheists are illogical.

Person2: Right. What an absolute joke!! For anyone who believes this nonsense I have a bridge to sell you. LOL

Argument from incredulity

The argument from incredulity fallacy occurs when instead of refuting an argument, a person will suggest that the argument is false (or true) because it is too difficult to imagine otherwise.

e.g.

Person1: Believing in things you can't justify is illogical. Philosophical atheists cannot justify their belief that God is imaginary. Therefore atheists are illogical.

Person2: So the greatest minds in science are illogical? Yeah right!

Arguments are bad when they're supported by poor reasoning not because they are ridiculed or because they are difficult for some to accept.
