The members of indie-pop trio fun. may be straight, but that hasn't stopped them from becoming fierce advocates of the lesbian, gay, bisexual and transgender (LGBT) community.

Now, it seems fun. wants to take its activism to the next level. As The Washington Post is reporting, the group is now hoping to establish a not-for-profit marriage equality organization. "We're firm believers in the idea that if you’re not talking about it, you’re part of the problem," guitarist Jack Antonoff told the publication this week. "We realize we have an audience, and it would be a real shame to waste it."

Of course, Antonoff, along with frontman Nate Ruess and keyboardist Andrew Dost, is no stranger to LGBT causes. In fact, Antonoff told Spinner in March that being heterosexual actually made their collective voice considerably more profound.

"Being part of a band of three straight men, we felt there was an inherent power in the fact that we aren't gay, and yet we still care and we have a voice -- there's a responsibility there," Antonoff is quoted as saying. "There are moments in history where it's vital [to have a voice] and anyone that is not standing up for the LGBT community is a huge part of what's holding them back."

In February, Antonoff also wrote at length about his passion for LGBT rights in a blog for HuffPost Gay Voices. "As allies, we have to prepare ourselves to step into the fire when necessary, even -- and especially -- when said fire is merely a still-lit cigarette tossed carelessly onto the street," he wrote. "Of course, the majority of us would speak up in the face of outrageous bigotry, but do we speak up in a social situation when someone casually refers to something as "gay"? If we don't, we are standing with the homophobes whom we are quietly fighting."
