The case of Abdul Razak Ali Artan, the Somali-born Islamic terrorist who ran over and stabbed 11 people with a butcher knife at Ohio State may be what President Obama calls a "teachable moment."  We can feel great sympathy for the victims, but it is also fair to point out that some of the policies advocated by said victims helped contribute to this tragedy.  And the fact is that a large number of Ohio State faculty and students are strongly pro-Islamic immigration.

Hollie Nyseth Brehm, an assistant professor of criminology (ironically), and student ​Abd Al-Rahman Traboulsi created an organization at Ohio State called "Refuge," bringing in putatively victimized foreigners to get a free education in America.

Refuge seeks to fill a unique niche geared toward addressing the extensive gap of resources available to adolescent refugees. Refuge's annual program then will culminate in an immersion experience here at Ohio State where refugee students will attend classes, speak with faculty and stay in residence halls – ultimately transforming higher education from a far-off aspiration to a feasible reality that adolescent refugees can take steps toward achieving. We hope that you will consider working with us here at Ohio State or with the many other local Columbus organizations that aid with the refugee resettlement process.

It doesn't take a great leap to conclude that "refugees" are not from Norway and Sweden; they are largely Muslims from the Middle East.  And Refuge is not the only Ohio State student group involved in this effort.

From clothing drives to tutoring sessions and mentorship programs, Ohio State student organizations such as the Syrian Student Union, Students for Refugees and Refuge: Empowering Adolescent Refugees are working to help those affected by the Syrian Civil War.

... the club hopes to expand its current program to offer more services, including a mentorship program, English as a Second Language classes, and move-in assistance for refugees arriving in Columbus.

The organization Refuge is a recent addition to OSU that sheds light on the Syrian conflict. A club in the making, Abd Al-Rahman Traboulsi, a third-year in biomedical engineering, said he is launching Refuge as a mentorship program to connect students at OSU with refugee students in the Midwest over an online interface, with the ultimate goal of introducing refugees to the possibility of higher education.

In other words, to bring them on campus.

Events are regularly held to propagandize the cause of bringing Islamic refugees to America.

No Lost Generation OSU & Syrian Student Union at The Ohio State University are hosting an #IStandWithRefugees event on the Oval. We'll have a wheel of fortune testing your knowledge on refugee crises around the world. Additionally, prizes may be rewarded

And yet one of these refugees tried to kill many of the same people who advocated bringing them to America.  I think it's appropriate to point out that the cause these people advocate is directly connected to the terrorist attack on 11 students.

This was perhaps best explained in the "poisoned skittles" theory by Donald Trump, Jr.

"If I had a bowl of Skittles and I told you just three would kill you, would you take a handful? That's our Syrian refugee problem," explained Junior's tweet, which was illustrated with a small bowl of the multi-coloured sweets.

He's right.  We don't know which Muslim refugee is radicalized or will become radicalized and try to kill us.  That's why we shouldn't let any of them in.  It's a lesson that even after this tragedy I'm afraid many of these advocates won't get, especially those members of the "Syrian Student Union."  The fact that there even is a "Syrian Student Union" at Ohio State shows the wrongheadedness of our refugee policy; Syria is in chaos, and refugees from there, like Somalia, are unvettable.

Just look at what a failed presidential contender had to say about the terrorist attack:

"At the end of the day we will find out what happened," Gov. John Kasich (R), who graduated from Ohio State in 1974, said at a briefing. "We may never totally find out why this person did what they did or why they snapped. We may never find out."

It's violent Islam, Governor Kasich.  And it appeals to a certain number of Muslims, and we have no idea who they are, and this will keep happening as long as we admit them to our country.

People who advocate for more Islamic immigration are like people who hit themselves over the head repeatedly with a hammer and then wonder why they have a headache.
