Islamism and Jihadism should be banned. Problem is that it is impossible to separate Islamism from Islam.
That is why this religion will have a really hard time to reform and eventually, it will fail. The question is not if, but when.
Are you sure about inevitable Islam collapse in the future? So far it's feel more like the other way around - Islam is spreading.
Mainly because of the rapidly increasing birthrate among Muslims and severe penalties for apostates.
I am more afraid of the future when Islam will spread so much and it'll become primary religion on Earth.
I would not worry about it. Our children might see it.
In the end, the truth always wins. If Islam dominates the world, we'll end up in a major economic collapse, followed up by a worldwide war.
I don't think Muslims will be able to kill 2 billion Chinese.
Islamists would block any technological and scientific progress and regress the conquered societies. They will start by eliminating all intellectuals, scientists etc. They will shutdown any progressive thought. Think 'Global Afganistán or Pakistan'.
Their global caliphate will fail. All bad ideas eventually fail. And Islam has a fair share of really bad ideas.
Before all this happens Sunnis and Shiiats would have to settle their differences. And that is not going to happen anytime soon.
Islamists will continue to change the laws and education systems in the West and stupid politicians will continue to accommodate them until they lose their support base. So expect Trump like elections in the years to come.
They can try but they won't succeed. And they'll still have Japan and the Koreas to contend with if they're ever to take over East Asia. Good luck shouting Allahu akbar in the face of a nuke. It's not like Kimmy would let them anywhere near his kimdom.
The world has forgotten about the threat of Islam but now with the internet every single atrocity would be seen by anyone on the planet. Once their growth spurt ends, they'll plummet down. Any potential convert by that time can just go online and look at all the vids.
