I am a pink hair pierced ears rebellious punk

Slippery slope is a type of fallacy that falsely assumes that one thing must lead to another.

They begin by telling that if we do one thing then that will lead to another and before we know it we’ll be doing something that we don’t want to do. They conclude that we consequently shouldn’t do the first thing. The problem with this kind of fallacy is that it is possible to do the first thing that they declare without doing the other thing.

For example, my parents have a tendency to use slippery slope in their argument.

“If you piece your ears, then next you’ll get a tattoo, and before you know it you’ll be a rebellious punk with pink hair and everything."

I don’t want to become a rebellious punk with pink hair.

Therefore: This argument commits the slippery slope fallacy because it is perfectly possible to pierce my ears without becoming a punk; I could pierce my ears and not get a tattoo.

The conclusion therefore hasn’t been proven, because the argument’s first premise is false.
