The Freedom From Religion Foundation is trying to “improve the image of atheists.”

Never mind much of their “image” problem is self-inflicted.

When it was proposed that a piece of leftover rubble, that many believe resembled a cross, be included as a part of the World Trade Center Memorial, the American Atheists organization released a statement saying, “The WTC cross has become a Christian icon. It has been blessed by so-called holy men and presented as a reminder that their god, who couldn’t be bothered to stop the Muslim terrorists or prevent 3,000 people from being killed in his name, care only enough to bestow upon us some rubble that resembles a cross.”

The statement provoked ridicule even from the likes of Jon Stewart.

Now, as the movement sets out on a mission to look better to the average American, FFRF is attacking Mother Teresa.

A few years ago, the group criticized the U.S. Postal Service for honoring Mother Teresa with a postage stamp.

The Isthmus reports:

But that wasn’t [FRFF co-president Annie Laurie] Gaylor’s only problem with a government-sanctioned honoring of Mother Teresa, whom she called an “extremist as a handmaiden for Roman Catholic global bans on contraception and abortion.” Gaylor says the nun “used her Nobel acceptance speech not only to preach against legal abortion, but against contraception.”

“There was criticism by the end of her life that she turned what was a tiny charity into an extremely wealthy charity that had the means to provide better care than it did,” Gaylor told Fox News in 2010.

“…There’s this knee jerk response that everything she did was humanitarian, and I think many people would differ that what she was doing was to promote religion, and what she wanted to do was baptize people before they die, and that doesn’t have a secular purpose for a stamp.”

“FFRF takes an extreme approach to separation of church and state, seeking to eradicate even the most innocuous traces of religion from the public square,” says Luke Goodrich, general counsel for the Becket Fund, a religious liberty organization.

And the Postal Service defended the stamp.

“Mother Teresa is not being honored because of her religion, she’s being honored for her work with the poor and her acts of humanitarian relief,” Postal Service spokesman Roy Betts told FoxNews.com.

“Her contribution to the world as a humanitarian speaks for itself and is unprecedented,” he added.

Mother Teresa died in 1997, so she wasn’t available to answer to FRFF’s new attacks.

FRFF says gays and blacks have had their shot at making gains. Now it’s the atheists’ turn.

“Gays have made great strides in popular culture. There have been seminal moments in TV for women, for black Americans, etc., and now it’s time for that seminal moment for atheist or agnostics,” Gaylor tells Isthmus.

She didn’t indicate what that “seminal moment” might be.

“Atheists tend to be demonized,” she says. “We don’t see the kind of violence that’s been directed at individual gays, but there’s always a rumble of threat against us.”

“Demonized” is the wrong word. Perhaps “ridiculed” is better and, interestingly, it comes from both conservatives and progressives.

“You’re a dick,” Daily Show correspondent Jordan Klepper – a self-described atheist – told FRFF co-president Dan Barker during a segment about the group’s effort to stop a privately-owned diner from offering a discount to patrons who prayed before their meal.

Reflecting on the incident, Barker tells the Isthmus, “When it comes to civil rights, there are indeed some issues that are more drastic than others. Lynchings and racial discrimination are clearly more horrible than being refused a discount because you don’t pray.

“But where do you draw the line? Do we allow a little bit of discrimination because some people feel it is only petty?”

That’s a good question and maybe one only a public relations firm can answer.
