Bombs Over the Middle East

I initially didn't want to post this because it's so offensive, but I figured if you ready my post about abortions and are still with me, this would give you a really good understanding of what I'm up against. I have begun to realize recently that my brother is not, as I previously thought, closer to me in general life belief and understanding, but much closer to my parents. I feel like this somehow got more pronounced after he had kids. I remember one time my mom, dad, and I were having dinner with him at his house. Sisterinlaw was at a work dinner or something. We were talking about terrorism, and my brother said something like, "All Muslims should die. All Muslims want to kill all Jews so we should kill them first" My brother is generally a smart, nice man so I figured he was just blurting things out, but when confronted he would backpedal. I tried reasoning with him that it can't be the case that all Muslims are hateful and want Jews to die, and sure there are a handful of Muslims who probably think that, but there are crazy Jews out there too, but he wasn't having any of it. I think the conversation ended with him saying "We should bomb them all" and me walking out of the room.
