False equivalence

I thought this one was quite funny…


It’s an “argument” I’ve seen often enough, but isn’t normally phrased quite so stupidly; it normally isn’t as obvious. Just because two things share one or more qualities, and especially if those are superficial or could have different meanings if expressed with different words, does not make those two things equal.

Bad debaters tend to hide this fallacious argument behind verbose use of language, mixed metaphors and scientific jargon. The guy who shared the above normally does all three… maybe he was lazy this time.

Of course this is a false equivalence, a type of logical fallacy.

Another one that makes just as much sense, and is equally wrong, would be:

Dogs are soft and cuddly.
Cats are soft and cuddly.

Therefore cats are dogs.
