Actor Josh Hutcherson says that much work remains in the fight for LGBT equality.

Hutcherson, a co-founder of the Straight But Not Narrow campaign, told E! Online that despite the recent Supreme Court ruling striking down gay marriage bans in all 50 states, his group still has a lot of work to do.

“There is still so much to do,” said Hutcherson (The Hunger Games, The Kids Are Alright).

“It's not only even about legislation. It starts there by making it legally acceptable. But socially, there is so much prejudice and bias that is integrated into our culture and that's going to be around for a while.”

“I hope that one day in my lifetime we get to close the door on this group, but there's a lot more work to do,” he said.

He added that hearing from young teens whose lives his group has affected has been rewarding and praised Caitlyn Jenner for her advocacy.

“I think it's fantastic for the LGBT community,” the 22-year-old actor said. “We need more people like that to share their stories, because once [transgender] people become more of the norm, it will be easier for people to socially accept it.”
