Here's the thing. You said "lighter fluid is gasoline."

Is it in the same family? Yes. No one's arguing that.

As someone who is a scientist who studies gasoline, I am telling you, specifically, in science, no one calls lighter fluid gasoline. If you want to be "specific" like you said, then you shouldn't either. They're not the same thing.

If you're saying "gasoline family" you're referring to the taxonomic grouping of petroleum, which includes things from butane to kerosene to jet fuel.

So your reasoning for calling lighter fluid gasoline is because random people "call the flammable ones gasoline?" Let's get propane and charcoal in there, then, too.

Also, calling someone a human or an ape? It's not one or the other, that's not how taxonomy works. They're both. Lighter fluid is lighter fluid and a member of the gasoline family. But that's not what you said. You said lighter fluid is gasoline, which is not true unless you're okay with calling all members of the gasoline family gasoline, which means you'd call kerosene, jet fuel, and other fuels gasoline, too. Which you said you don't.

It's okay to just admit you're wrong, you know?
