Conservative commentator Ann Coulter stopped by HBO's "Real Time with Bill Maher" on Friday to continue spreading her gospel of anti-immigration and xenophobia while promoting her new book.

Also featured on the talk show's panel was Democratic Congressman Luis Gutierrez and MSNBC TV host Joy Reid. However, that didn't stop Coulter from reasserting all of the controversial claims that she made in her book "¡Adios, America!"

"We used to have an immigration policy where we would choose the best in the world, and that was changed," said Coulter, arguing that the influx of Hispanic immigrants is hurting America.

"Well, we would choose the whitest in the world," Maher rebutted.

"Look, the pre-1970 immigrants were more educated, made more money, were more likely to buy houses, and 30 percent of them went home," Coulter said.

"Now, no one goes home, they go on welfare, and they are far more likely to be on welfare than the native population, I think a nation's policies should be concerned with the people already here, and that includes the immigrants who came last year and the year before. It should be people who live here benefit, not to become the battered woman's shelter of the world, where we're bringing in the hardest cases, and the wife beaters, and single mother with eight kids."

Maher and Coulter also debated the number of undocumented immigrants that currently reside in the U.S. The U.S. Census Bureau states that the number is around 12 million; however Coulter argues the number is closer to 30 million.

"The point and issue is, should America's immigration policy be used to benefit the people already here? Or should it be benefiting Pakistani push-cart operators -- illiterate in their own language, never mind ours -- who come here, go on welfare, commit terrorism, engage in crimes?" the author said.

Eventually, Gutierrez jumped into the debate, making note that Coulter's anti-immigrant rhetoric will backfire against the Republican Party. By demonizing Latinos, he argued, Coulter and other conservatives like Donald Trump are "revving up ... a Latino registration machine," who will in turn vote against Republicans.

"What I think that Ann Coulter is actually doing wrong, along with Donald Trump, is revving up a Latino registration machine," the Illinois representative said. "You're never gonna take the White House with this kind of politics ever again."

MSNBC's Joy Reid also took exception to Coulter's "negative characterization," pointing out that both of her parents immigrated to the U.S. from different parts of the world.

"I'm a first-generation American, and I'm fully American, despite the fact that both my parents were born outside the U.S.," she said.
