Proponents of human rights and LGBT equality had a lot to celebrate this year when the United States Supreme Court ruled that state-level bans on same-sex marriage were unconstitutional. Sadly, not all of the world's on the same page, a lesson Adam Lambert is learning the hard way.

But he's not accepting any discrimination quietly.

According to The IndependentLambert, who's scheduled to perform as part of Singapore's New Year's Eve Countdown special, has become the target of a petition to remove him from the schedule. More than 20,000 have signed the document that claims his "promotion of LGBT rights" is inconsistent with "Singaporean values," and argues he would be "hardly the kind of performer to send off our historic Jubilee year."

Rather than condemn the movement, Lambert took the opportunity to respond via a note on his Singaporean record label's Facebook page, through which he continued to canvass for equality.

"My performance at Celebrate 2016 will not only be a spectacular one, it will celebrate the entire human family in all its diversity," he said. "I am a uniter, not a divider, and I believe in celebrating the human heart and spirit."

And the message certainly hasn't fallen on deaf ears. A counter-petition to keep Lambert on the docket has since manifested and boasts nearly 25,000 signatures. "Fight against bigotry and homophobia!" one note reads. "Don't embarrass Singapore with a few ignorant fools."

What do you make of the Singaporean petition? Sound off on the story in the comments below.
