The funny thing is that those Muslims most likely to deny the Holocaust are those most likely to enjoy Hitler and talk of a second one. If the first didn’t happen how can you be so nostalgic about it?
They’re engaging in sophistry. They KNOW the HOlocaust happened, they just like to divert the energy of their opponents into the rhetorical morass so that they can advance their cause even further. It’s not about what’s true, it’s about refusing to acknowledge the truth that benefits your enemy. In that, they are very much like the political Left.
