That whole line of questioning is a HR nightmare and I don't think they'd get away with it in any large company. You are _not_ supposed to ask open ended questions that could reveal a candidate as a member of a protected group. They tell you that their parents kicked them out because they were gay, they don't get hired, and they file a lawsuit saying that there were forced to reveal their sexual orientation and they were discriminated against because of it. It'd be a pretty easy win.
