Refusing to rent to someone LOL

[Roger S.]

So, today, my wife gets a call from an ex boyfriend that she dated before we met.   10 years ago or more.  He's looking for a rent house.  She tells me he's manipulative, he's getting a divorce, and she doesn't want to rent to him.  Well, neither do I.  He sends her a text telling her he'll pay a full year cash up front.   

I send him a text telling him we don't have a home for him, and not to contact my wife again.  He sends me back a text, all huffy, about how it's not real smart to deny a qualified renter by electronic communication, like he's making a threat.

I told him, unless he's a member of a protected class, i can tell him to take a flying %$#@.     LOL.  So far, I've heard nothing else.   

What would you have done?
