One of the biggest objections that sane people have to Muslim immigration is that an unknown number of immigrants are, in the words of Donald Trump, Jr., poisoned Skittles who will commit acts of terrorism.  This "poison Skittle" problem is a very valid concern, but not the only one.

The fact is that a much greater percentage of Muslims, who may not commit terrorist acts, nonetheless are in favor of imposing sharia law in the area where they live.  One poll said 40% of Muslims in Britain want sharia enforced.

Knowing that, it should come as little surprise that over 1,000 Muslims marched in London, demanding the establishment of an Islamic caliphate – in Great Britain.

Over a thousand British Muslims took to the streets of London on Tuesday in a show of force, blocking off a central London square to call for a caliphate while the crowd chanted ‘Allahu Akbar’

We need a Caliph who will clean up these streets / Who will smack up armies and who will back beef [fighting]. / Backhand your missiles back to your land, that’s the plan. / World domination at hand. We can expand and take out these fools.

Those were the words of a poet invited to address the raucous crowd outside the Syrian Embassy in central London who cheered and yelled Allahu Akbar (Allah is the greatest) in support of his calls for war.

The crowd, mostly drawn from mosques across London, was largely self-segregated with many of the women wearing Islamic clothing.  It soon grew to block off the entire road, with many in the crowd waving what looked to be the Taliban flag, while others were handed placards made by Hizb ut-Tahrir Britain, which calls for the reestablishment of a caliphate.

When 40% of a population group supports something, like sharia, there is no vetting out such a group.  You can't separate the religious Muslims who want to practice their religion only for themselves from religious Muslims who want to impose it on others.  There simply is no test for that.

That's why, as I've said before, immigration from Muslim countries must stop until the aggressive attitude of Islam changes.  If there are refugees from countries in conflict, why can't they go any of the other dozens of Muslim countries not in conflict?  Because at the heart of it, most of them are economic refugees, and they want to colonize the West and make it their own.

This demonstration, and the polling behind it, challenges the media's narrative that the vast majority of Muslims are "moderates" who simply want to practice their religion in private and leave everyone else alone.

What will be the end result of such immigration?  You'll find calls to prayer blaring out over loudspeakers at 4 AM, as you can in some neighborhoods near Detroit, and radicalized Muslims patrolling the "no go" zones where the police are afraid to go, harassing anyone who isn't sufficiently devout.  That's why we need to stop Muslim immigration now.
