I would rank Islam as more evil than Socialism, Communism, Nazism, or any other movement in history. Oh sure, those left-wing movements have killed over 100 million people, but Islam will eventually dwarf those. It is far more dangerous because it is a religion, it is spread across the entire globe, and there is nothing peaceful about it. There are about 1.5 billion Muslims spread out over the world. The vast majority are decent folk, but when religion is involved, even the slightest incident can turn most decent folk into something very dangerous. Once Islamic controlled countries get nuclear weapons, the world will be a very different place. We can sit back and ignore it, or we can try to stop it. It should be our highest priority to ensure that no Islamic country gets nukes, but Iran is almost there. IMHO, sitting back and not getting involved is not the answer.
There is no historical evidence to back up such an assertion. It is pure conjecture.
It is far more dangerous because it is a religion...
How does that make a difference? I hope you're not implying that religion has any more culpability in promoting violence than any other factor. That is a canard that can easily be refuted.
The vast majority are decent folk, but when religion is involved, even the slightest incident can turn most decent folk into something very dangerous.
Evidence? Once again, this is wild conjecture based on a popular but false notion that religion causes violence.
Once Islamic controlled countries get nuclear weapons, the world will be a very different place.
How so? Will they suddenly have the abilities, namely delivery systems and consistent weaponry, that most of the rest of the nuclear club does not?
