Matthew Morrison, who plays Will Schuester on the Fox musical-comedy hit Glee, says the show promotes that being gay is OK.

The 32-year-old actor was in Washington on Monday to perform at the Capitol Fourth Concert, which was broadcast on PBS.

Glee's inclusion of four central gay characters – closeted lesbian student Santana Lopez, played by Naya Rivera; openly gay student Kurt Hummel, played by Chris Colfer; closeted gay football player Dave Karofsky, played by Max Adler; and openly gay student Blaine Anderson, played by Darren Criss – along with several peripheral gay characters – Rachel Berry's yet-to-be-seen dads and coach Sue Sylvester's evil accomplice Sandy, also known as The League of Doom's Pink Dagger, for example – has earned it the nickname “the gayest show on television.”

The show is so popular and everyone watches it, it just kind of helps promote that it is okay to be [gay] … it's like that Lady Gaga song, you know, you're born this way and be proud it,” Morrison told gay weekly Washington Blade reporter Steve Fox.
