HOLLYWOOD, CA – A new survey from the Hollywood Reporter says that greater visibility of openly-gay characters on primetime television is having an impact on the attitudes of Americans towards LGBT rights, and not all of is it good.

With major storylines involving LGBT characters on hit programs like “Modern Family,” “Glee,” and “The New Normal”, 27 percent of TV viewers responded that gay exposure made them more supportive of marriage equality, while 12 percent admitted to being more negatively disposed to same-sex marriage.

As expected, the survey results broke along party lines, with Obama supporters twice as likely to watch “Modern Family” (ABC) as Romney supporters, twice as likely to watch “Glee” (Fox), and three times more likely to watch “The New Normal” (NBC).

The poll also said that Romney supporters are five times more likely than Obama supporters to stop watching a program if a gay actor is portraying a straight character (25 percent vs. 5 percent), and nearly eight times as likely to stop watching if a straight actor plays a gay character (30 percent vs. four percent).

Last month, the Gay and Lesbian Alliance Against Defamation (GLAAD) released its annual report, “Where We Are on TV,” which shows that a record 4.4 percent of regularly-appearing portrayals in the 2012-2013 season will be of LGBT characters, an increase from 2.9 percent in 2011.
