Another year has gone by and another tax deadline is in the rear view mirror. While billions of Americans made some sort of taxes in 2015, one group didn't; churches.

Dodging the IRS

The current national debt is approaching $20 trillion, with an average debt per citizen at $59,200, and $160,892 per tax payer. With a debt climbing even when the yearly deficit is shrinking, the United States government are deadlocked on how to fix the problem. According to the most recent calculations, in particular out of the University of Tampa and professor Ryan T. Cragun, churches would contribute $71 billion a year if their tax exempt status was revoked.

While it wouldn't eliminate the debt, it would contribute to tackling the problem. This issue was the highlight in Bill Mahers' latest rant during the April 15 edition of HBO's "Real Time with Bill Maher."

Maher says tax the churches

"Now that it’s April 15,” Maher said, "U.S. taxpayers must call out the deadbeats who ride for free, which includes giant corporations like GM and United Airlines, which this year are going to pay no taxes."

Referring to Religion as a "sexist" and "homophobic magic act," Maher noted that it's "been used to justify everything from genital mutilation to genocide." "You want to raise the tax on tobacco so kids don't get cancer, OK.

But let's put one on Sunday school so they don't get stupid."

In conclusion, the liberal comedian pointed out that nearly a quarter of Americans are not even a part of a religion, including 35 percent of millennials. "Almost a quarter of us are being forced to subsidize a myth that we're not buying into," Maher continued, asking "Why am I subsidizing their Sunday morning hobby?"

Religion in the United States

Though the United States is not a Christian nation, despite what many in the GOP often note, Americans have generally been religious. However, in recent years, religion and the literal belief in God has been on a steady decline. According to recent polls by Gallup, the percentage of Americans who believe in God has dropped off over the last 50 years. In 1966, 98 percent of Americans believed in God, compared to 86 percent in 2014. That number is even lower, 80 percent , when asked to millennials. When it comes to Christianity, only 70 percent of Americans now follow the teachings of Jesus Christ. The group that has actually increased is what is known as the "nones," or people who have no religious affiliation at all, as nearly a third of Americans now say they have no allegiance to any church or religion.
