The openly gay TV writer has admitted highlighting homosexual relationships and minorities in the musical comedy series has angered many people and they have shown their displeasure by sending him threatening.
He told Deadline: ""I've gotten death threats, yes. I have. I think anytime you shine a spotlight on homosexuality or minorities and you try and say they are as normal or as worthy as acceptance as others, the people who are on the fringe don't like that and they will come after you. And they have come after me. I think it's such a great show for young kids. The values of it, I think, are great."

That's when I got interested in looking at the impact that we possibly can have and what can we do with that.
I think it's a great gift when I go to those Glee concerts and look out into the audience and see 20 people in wheelchairs who've been driven by their parents across three states because they see someone who looks like them who's cool. That is an amazing unexpected gift of the show that we take very seriously."
