Why was it rude? Was your correction rude simply because your explanation (which is valid by the way, nice catch. I was more focused on the fact that it sounded weird, not why) was more in depth? You’re also weirdly latching to the whom when my focus was the in pronoun group choice, as in: where are those whom who**.

I don’t correct out of rudeness. Making assumptions makes you look more of an asshat than correcting someone. I want people to correct me. As I said, nice catch.
