Let's start with a little background information.
The man behind its construction, Essam Fathy, told a whole series of lies about how long construction would take. He claimed years, seemingly to garner sympathy to realize a dream, and that just getting the site leveled and the parking lot paved would take one or two years alone. Instead, construction was very rapid.
Back to the U. S. Department of Justice's lawsuit. Despite the imam being tied to the MUSLIM BROTHERHOOD, and other serious questions about the ICM, a department memo was quoted as saying the allegations accusing the ICM being connected to a terrorist organization are "unfounded." Really. The Muslim Brotherhood is not a terrorist organization. OK. Glad we were able to clear that up. (SOURCE 4)
Statements from the U.S. DOJ get even more ludicrous. Assistant Attorney General Thomas E. Perez of their Civil Rights Division said, "Our nation was founded on bedrock principles of religious liberty. The Department of Justice will continue to vigorously enforce civil rights laws that protect religious freedom. The U. S. attorney for the Middle District of Tennessee, Jerry Martin, said, "The United States Attorney's Office will zealously protect every citizen's right to worship and assemble." " If that's the case Mr. Perez and Mr. Martin, why didn't the U.S. Department of Justice rush to Phoenix, Arizona and file a lawsuit against the city where Michael Salman was prosecuted, convicted, sentenced to sixty days in jail, two years probation, and a $12,000 fine for a having a Bible study on his own property?
Mr. Martin and Mr. Perez apparently don't understand their own doctrine of the mythical separation of church and state. No matter how it's justified, no matter how you look at it, the U.S. Department of Justice has filed a lawsuit on behalf of a religious organization. Just where is the hue and cry of the liberal left wingnuts screaming about "separation of church and state? Where is the Freedom from Religion Foundation and the ACLU?"
One last thought: If this were a Christian church, does anyone really so delusional to believe the U. S. Department of Justice would have raced in to file a lawsuit to force a local government to permit occupancy of the building in time for a religious observance or holiday? Not a chance.
