Is Mr. Beck trying to bash Christians by the above article?
No. I believe he's just trying to better explain Islam and what we have to deal with in trying to defeat them.
When Islam was invented, most of the Middle East was Christian, so there’s no surprise that it should have an altered interpretation of Christianity.
Beck’s point is how deeply Muslims believe things not immediately apparent to outsiders, and how the MSM/White House wants to cover up those beliefs.
When Mormonism was invented, most of America was Christian, so there’s no surprise that it should have an altered interpretation of Christianity. I believe Joseph Smith said as much.
