"They" are doing the reminding, and "they" = "who".

I understand what you're saying but I'm pretty sure that's not how this one would pan out. There's a preposition there. Where there's a preposition, you get whom, him, them. Apply the old "never end a sentence with a preposition" rule and see what you get.

Yes, but we're talking about the object of the preposition "of"; "they" is the subject of remind. So it really is "Whom do they remind you of?" If you give in to the arrant nonsense up with which Winston Churchill would not put and recast it as "Of whom do they remind you?" perhaps it is clearer that "whom" is called for. Also, the advice of the original post still holds. English speakers wouldn't say "Do they remind you of I?"

"They" are doing the reminding, and "they" = "who".

Nah... "They" are reminding you of "whom". "Who" may be reminiscent of "them", but ultimately "they" and "who" and "you" are separate but equal remindatory entities under the law, Amen.

Okay, definitely time for a beer... Or five...
