I am well educated about the US Muslim Brotherhood, having read 25 well-researched books on them and Islamization in general, over the past 11 years + thousands of their footnotes. I don't need any coaching from Rush or Beck or anyone. As for "the Islamic faith", I've read quite a few translations of the Koran, since 1959, most recent these >> Pickthall, Ali, Arberry, Shakir, and Dawood.
Frankly, though for what is relevant about Islam fundamentally, as threat to America, one would only need to read about a dozen suras, which could be accomplised in a half hour. They might also take note that Islam doesn't reform itself (as Christianity did some centuries ago). That's because Muslims believe that the Koran is the word of God, and that can't be changed.
Result ? Over the past 1400 years of the existence of the Koran, not one word of it has been changed.
And since I'm new here now, I'll just say that I hope one thing that is NOT avoided here is the TRUTH.
