TWO WRONGS MAKE A RIGHT Argument used to distract attention from a

wrongdoing by claiming that similar actions went unnoticed or unpunished.

Why bother trying to conserve energy? China is opening a new coal burning power plant every day. If they’re not doing their part to prevent climate change, why should we?

So what if I don’t separate the cans and newspapers out from the garbage for recycling? I don’t have that much time. Neither do most other people.

HASTY GENERALIZATION

An all-inclusive statement made in “in haste” without allowing for exceptions and qualifiers.

If you’re in the market to buy a dog, don’t get a Shetland collie. All of them are nervous and high-strung. My friend, Pamela, has one and that dog yaps at every little sound.

Producing one calm Shetland collie negates the argument.
