I thought The New Normal took a while to warm up, but it's become a great show, with funny characters, well-written dialogue and decent themes.
I think a lot of homophobia comes from people who don't have any/many gay people in their lives. This ensures they don't really understand what it's like to be gay. Shows like this go a long way toward normalising homosexuality, and allowing people to recognise the great number of similarities between heterosexual and homosexual couples.
Plus, it's loaded with great pop-culture references, endearing characters and some pretty clever metaphors. One of my favourites is the metaphor evident in Shania's wedding: the adults in the show attempt to forbid a wedding between two children, just as religious authorities have attempted to forbid marriage between homosexual couples. The message: religious authorities are treating us like children. Clever.
