This is not to defend Spencer's utterance of those things. I would never defend comments like those. But they should be taken in context. Which was (as I understand it) that he was speaking into another guest's mike and attempting to jokingly defame that guest by saying the most deplorable things he could think of. Why he did this is a mystery, it was just wrong, shows bent thinking, and obviously he couldn't have seriously thought that his ploy would work and that those remarks would be attributed to anyone else just because he used their mike. He would have to fool the cameras, too.
So he has a bent sense of humor (I’ll call it that), not appreciated by myself, you (I assume), or anyone else. But in that context, he is not advocating the practices of which he spoke, or saying that they are what he does. It was a just terrible joke in shockingly bad taste. And of all the things said in the house this year, that really takes the cake, and is what he will probably follow him in post-BB15 life.
He's said some other stuff that was pretty racial and misogynistic, too, so Spencer doesn't deserve to be let off anyone's s--- list.
