Sorry, I forgot to mention that he went on to say how disgusting gay sex is. Does that leave any room for doubt?? He may not be outright hostile to GLBT folks, but I was still offended by his remark. He's ignorant if anything.
I feel it's best in this case to let it go, because it's not something he rants about all the time, it's taken four months for the subject to come up and probably won't again. There is a time to speak up, but as the saying goes we have to choose our battles wisely.
