Last night on "Real Time," HBO host Bill Maher described himself as a "proud liberal," but said it's "crazy" that President Obama and his administration won't criticize Islamic practices or use the term "Islamic extremism."

Congresswoman Tulsi Gabbard (D-HI) agreed, saying that "words mean things" and are important to identifying and defeating the enemy.

"By saying that they're looking for thrill-seeking or that economic prosperity will solve the problem -- give them a big house, give them a skateboard, send them on their way --  you think that's going to solve the problem? It's not," Gabbard said.

Maher noted recent uproar over Canada's new citizenship guide using the term "barbaric" to describe practices like honor killings, forced marriage and female genital mutilation.

"I don't know why we can't call out this stuff for what it is," Maher said.

He said that liberals "start with this premise in their head that all religions are alike, all cultures are alike, it's a religion of peace, everything is pretty much equal, don't judge. But they don't really have knowledge of it."

"It's this philosophy that gets in the way of us being able to accomplish our mission and defeat those who are threatening us," Gabbard said, who served in Iraq with the Army National Guard.

"It goes to the problem of not really recognizing there actually are things that are right and wrong. And these honor killings and other things, they are clearly and absolutely wrong."
