The fourth-largest matchmaking Web site is being sued because it pairs only heterosexual couples.
Linda Carlson of California sued eHarmony in Los Angeles County Superior Court after she tried to meet a woman on the site this year. The suit claims eHarmony violates a state law barring discrimination based on sexual orientation.
Neil Clark Warren, founder of eHarmony, told USA Today that his site promotes heterosexual marriage, about which he has done extensive research. He said he does not know enough about gay and lesbian relationships to do same-sex matching.
It "calls for some very careful thinking. Very careful research," he told the newspaper. He adds that same-sex marriage is illegal in most states. "We don't really want to participate in something that's illegal."
