Is the phrase “left-handed compliment” considered offensive against left-handed people? Wikipedia and Wiktionary don't mention it being offensive, but I want to make sure.
I’m aware of “two left feet” to indicate that someone’s a bad dancer, but that’s describing yourself, and you may actually be right-handed, whereas “left-handed compliment” may be describing the speech of someone else who may or may not be right-handed.
I’ve also heard of sinister, but a person using the word could reasonably claim that they didn’t know that it is derived from left-handedness.
