Doubt the veracity of a claim about a discussion on gay oral sex in someone's daughter's class and criticize the use of hyperbole in making a point.
Need reliable evidence that they talked about gay oral sex in your daughter's class. Your word is not to be trusted. I'll believe that they talked about gay relationships, but I'm not inclined to believe that got into pornographic details. My guess is you use hyperbole to make your points, as you know of no other way. Oh, and cover your daughters eyes, ears, and groin area till she's 25. Judging by your comment, your daughter probably knows more than you regarding a wide range of subjects; but, sadly, children don't get to choose their parents.
