NRA magazine, Celebboutique.com delete tweets after Colorado theater shooting

The American Rifleman, the joual of the National Rifle Association, has deleted a tweet that appeared to make light of Friday's shootings in Aurora, Colo., during a midnight screening of "Dark Knight Rises."

"Good moing, shooters," the message, published at 9:20 a.m. ET on the American Rifleman's Twitter feed, read. "Happy Friday! Weekend plans?"

Not surprisingly, the tweet sparked considerable outrage, with hundreds of users--including Michael Moore and Keith Olbermann--pointing their followers to it.

The American Rifleman deleted the tweet several hours later but has yet to issue a formal apology.

It's unclear whether the tweet was intentionally insensitive, or if the magazine's tweeter was unaware of the shootings that left 12 dead and 50 wounded.

"Is there a way they wrote this without seeing the news?" Audrey Wauchope asked on Twitter.

"This is what happens when you don't read the news," the Columbia Joualism Review said.

In a statement to CNN, a spokesman for the NRA said that "a single individual, unaware of events in Colorado, tweeted a comment that is being completely taken out of context."

The NRA wasn't alone in appearing insensitive to the tragedy.

CelebBoutique.com--"the online boutique loved by your fave celebs"--took the shooting as an opportunity to promote its Kim Kardashian inspired dress:

"#Aurora is trending, clearly about our Kim K inspired #Aurora dress ;)," the boutique wrote on its Twitter feed Friday afteoon. "Shop: http://t.co/IYGHqVsK."

The shop did not immediately respond to an email from Yahoo News seeking comment.

"Classless," Ken Fang wrote on Twitter. "Just classless."

Earlier Friday, author Salman Rushdie faced a backlash over comments he made on Twitter following Friday's massacre.

"The 'right to bear arms' is the real Bane of America," Rushdie wrote in an apparent reference to Bane, a character in the blockbuster film who some witnesses speculated the suspected shooter was dressed as at the time of the shooting.

That wasn't quite as offensive as Republican Rep. Louie Gohmert, who chose to link the Aurora shootings to an assault on Judeo-Christian values.

During a radio interview Friday moing on the Heritage Foundation's "Istook Live!" show Gohmert was asked to explain why he believes acts of violence such as this one take place.

"You know what really gets me, as a Christian, is to see the ongoing attacks on Judeo-Christian beliefs, and then some senseless crazy act of a derelict takes place," the Texas congressman told host and former Republican Rep. Eest Istook.

Gohmert later said some of his comments from the interview were taken "out of context."
