During last week's episode of "Real Time with Bill Maher," the irreverent comedian blasted GOP presidential candidate Mitt Romney for donating money to the Mormon Church rather than to a more worthy charity. Instead of reigning in his attacks on Romney and Mormonism, he sharpened his criticism during his New Rules segment in Friday's broadcast of HBO's political comedy show.Maher brushed off the Internet firestorm that came from the right after last week's episode, saying that he's "really sorry if I called your horseshit bullshit." He once again emphasized that he believes Mormonism is a "cult," quipping that "I personally define a cult as any religion with fewer followers than Snooki has on Twitter." (For the record, the Church of Latter-Day Saints counts about 14 million members among its ranks, versus Snooki's 4 million Twitter followers.)But he mostly took issue with the practice of tithing, which asks Mormons to give part of their earnings directly to the Church.
