I'd let it go. I wouldn't respond to his e-mail. I've always found that the best way to get a message across to someone is to ignore them. He is not the sort of person I care to do business with.
I would find someone else to handle all my affairs and write this guy off.
True, and all I asked him was "What about REITS" or "What do you think of REITS", I was asking for his opinion and professional expertise. It's not like I said "Ohhh I think REITS are GREAT, what do you think?"
He called me ignorant and uneducated just because I asked him his opinion. It's his job to give it to me! Obviously I'm not an expert because I don't live and breathe investments. It was only a question. And there's a saying that goes something like "There's no such thing as a stupid question except one that isn't asked" or something similar.
