But YouTube isn't the only site raising the ire of some conservatives.
Wikipedia, Jimmy Wales' Internet encyclopedia, also has some conservative competition on the Web. Conservapedia.com was founded in November 2006 by Andrew Schlafly, son of conservative activist Phyllis Schlafly.
A statement on the Web site reads: "It's time for the conservatives to get our voice out on the Internet!"
On Conservapedia, a search for "global warming" yields a definition that states, in part: "The scientific theory is widely but not universally accepted within the scientific community."
On Wikipedia, that same search yields a definition of global warming: "The observed increase in the average temperature of Earth's near surface air and oceans in recent decades and its projected continuation."
The difference in approach -- a classic "wiki-war" -- is not uncommon, and Rainie suggests that the conservative alternatives are natural outgrowths of the Internet.
"The Internet is all about niches," says Rainie. "It makes perfect sense for all kinds of groups that are organized by partisan belief and passion to create their own channels."
