Both "I could care less" and "I couldn't care less" originate from the mid 1900s (one in the 40s and the other the 50s) and have been used by many interchangeably. Some use it as a sarcastic version, others find irony in it. For many it is simply an idiom they have heard and use. Anyway, whatever the reason many more people use the phrase than you want to give credit to, and it is much more accepted that you seem to want to believe. But don't take my word for it. Simply google the phrase.

As for hardy, good for him. Now let's lock him up long term.
I appreciate your response. However, after reading your links, it's interesting that the author (and other sources) notes the use of the phrase "could care less" is ...
1.) A Yiddish form of humor and
2.) is subject to intonations (intonation, by the way, is a word that implies
sound)
Now, unless the original poster is Yiddish, then it should be "couldn't care less". Intonation is not an issue because we're typing not talking to one another.
Furthermore, from dictionary.com
Many native English speakers, both in the UK and US, find this expression to be logically flawed. If you couldn’t care less, then you care so little about something that it would be impossible for you to care any less than you do. If you could care less, however, you are saying, literally, that it is possible for you to care less than you care now. Those who take issue with this believe this later variant says very little about your level of caring, and so eschew it.
Different words and phrases have different meanings in other languages. Also words and phrases evolve over time. When using a particular word or phrase, it is good to note how it is used more commonly in a particular language. The more common use of the phrase is "couldn't care less" particularly in American English. Oh, I'm sure one can find a more obscure alternate to apply (which can be said about anything, really), but the way the phrase is commonly used is "couldn't care less."
And, yes, I Googled it, along with use my own knowledge as a former English assistant teacher.
