I just need to clarify

I just need to clarify something… The expression “I could care less” means you do care. Think about it. If you could care less, then you currently care more than you could potentially care. The expression you’re probably looking for is “I couldn’t care less.” At that point, you allegedly have the least amount of caring in your tank you can possibly have while still having some amount of caring. Which brings me to this point — the phrase “I don’t care” seems to be best suited for most of those misusing the English language in this way. It seems more resolute and firm since it communicates a complete void of caring, whereas even “I couldn’t care less” potentially implies that miniscule level of caring just above zero (there’s a name for that sort of thing in calculus language, but I dropped that class at semester and took wood/leather/plastic work instead.)
