I recently learned (in my mid-40s) that I’ve been figuring this out the hard way most of my life.
I always diagram the sentence in my head, as in: The subject is fear, the object is Rush, so it’s ‘whom.’
My wife has a simple grammar rule that if him/her
works then it’s whom, if she/he
fits better then it’s who.
I feel like my primary school teachers did me dirty.
I just assume that if what you’re referring to is “them”, it’s “whom”.
I cannot learn otherwise, I am too stupid.
Man, I wish universe had a longer run.
I think it’s more technically correct as “of whom are you afraid” as you should not end a sentence with a preposition.
Then again, I’m a software engineer so perhaps not.
Bork, you’re a Federal Agent. You represent the United States government. Never end a sentence with a preposition!
It’s fine to end a sentence with a prepositional or phrasal verb. https://www.grammarly.com/blog/end-sentence-preposition/
