To answer another question of yours, as to whether the intention is to take over the US government. I believe the answer is clear. It might further interest you to know that the country FUNDING your eventual conversion is Saudi Arabia.
Perhaps your remember Siraj Wahaj, he was the first the first imam to deliver a Muslim prayer for the U.S. House of Representatives, he also just recently addressed an audience of New Jersey Muslims, that they could take over the United States and replace its constitutional government with a caliphate. He said "If we were united and strong, we'd elect our own emir [leader] and give allegiance to him...Take my word, if 6-8 million Muslims unite in America, the country will come to us."
Absolutely right...
read my article concerning the Archdiocese of Rockville Center. Alas, I mis-spelled Archdiocese, but if you do a search by poster Milford421, you will find it. Unusually strong connection between the ISNA and this mosque. Don't forget, the ISNA picks the chaplains for the military. They've also recently had their tax records seized by the government investigating terrorism ties.
