Islam definitely combines the finest parts of nazism, warlordism with a claim of spiritual beliefs. To some limited extent, it can be considered a religion, but it is more than that, as you know. For that reason, because it is not just a view about the cosmos, but about what to do to other people, including us, then it must be met head on as an ideology as well. When we fought communism, we didn't just war with it, we engaged it intellectually, and, in spite of the left, got the better of the argument among those with half a brain. Very few pretend to argue that Marx got it right any more. Similarly with Hitler or Mussolini or Tojo. Their ideologies are in the dustbin. That's where we need to put Islam. While killing off as many of the radical ones who are currently attacking our civilization as possible.
Thank you. That was just distilling it down to its simplest form based on its origins. Each point is provable beyond any question. There are many more barbaric tenets that could be added each one bolstered by citing Muhammad’s personal participation.
Strip it of its pretense of being a legitimate religion or spiritual tradition then debate its merits as an ideology.
