Grammar and spelling flames are usually content free posts, and so you may find your post attracting downvotes. (Not from me.)

I understand that people hate the phrase "could care less".

I could care less is acceptable[1] US usage. It's been around for a surprising amount of time. "Couldn't care less" is from about 1946; "Could care less" is from 1960s.

[1] It is baffling and it's not something I would ever write. While I try (and often fail, with terrible punctuation) try be correct with my English I am very tolerant of what other people write. Especially on a site where many people are not speaking English as a first language.

>I could care less is acceptable[1] US usage.

Not true. It's incorrect and therefore not acceptable.
