Good news, homophobes: The 2010 Census is going to make homosexuals disappear. Well, OK, they will still exist, just not officially. That's because the census will neither ask about sexual orientation nor recognize gay marriages, civil unions and domestic partnerships. Married same-sex partners with a child won't even be considered "families." The U.S. Census Bureau simply isn't interested in a person''s "lifestyle," explains spokesperson Cynthia Endo, "This is all about the numbers" -- and gay people just don't count.
