How many kicks in the head will it take for western nations to learn that Muslim immigration is worst public policy ever?

Today’s example is the terror attack on a Sydney cafe where a couple dozen people were taken hostage by an Iranian, Man Haron Monis, who was accepted as a refugee in Australia in 1996.

Below, a hostage delivers a message from the terrorist that he was attacking Australia in the name of the Islamic State (ISIS):

The guy has a rap sheet filled with violence including dozens of sexual assaults on women through his spiritual ministrations as a sheikh and arranging the murder of his ex-wife. Why was such a violent man allowed to walk the streets?

Below, Sheik Haron apparently likes media attention.

The spin coming out is that Monis is mentally disturbed, and he may well be from a western psychological viewpoint. But Islam encourages violence against infidels, and for that reason is attractive to the criminally minded.

For example, the Islamic prison ministry in this country has gained thousands of converts to the most radical form of the bellicose religion, like the Oklahoma prison convert who beheaded a co-worker in September.

Meanwhile, liberals were worried about backlash toward Allah’s gangsters at the same time that lives were being threatened:

#illridewithyou supports Muslims amid Sydney siege, AFP News, December 15, 2014 Australians came out Monday in solidarity with the Muslim community following a siege at a Sydney cafe, as tens of thousands tweeted the hashtag #illridewithyou to counter concern about an anti-Islam backlash. The hostage-taking at the Lindt chocolate cafe triggered a security lockdown in the heart of Australia’s biggest city, with the government and Muslim leaders condemning the attack and calling for unity. Amid uncertainty about the hostage-taker’s motives and fears of reprisals after an Islamic flag was raised in the cafe, an Australian woman reportedly started the #illridewithyou hashtag to show solidarity with Muslims who might feel threatened on public transport.

The danger to the public would not exist if the government had not allowed thousands of Muslims to reside inside the gates.

Here’s a local report about the jihadist’s background:
