An event central to this month's 'Ex-Gay' Pride Month has been canceled.

Organizers said on Monday that their July 31 Lobbying Day on Capitol Hill and Evening Dinner/Reception was being postponed due to “security threats.”

“Due to some anti-ex-gay extremism that has occurred since we first announced Ex-Gay Pride 2013, the July 31 Lobbying Day on Capitol Hill and Evening Dinner/Reception at the Family Research Council has had to be moved and postponed to an undisclosed location in September,” Voice of the Voiceless said in a blog post. “The harassment has caused several security threats which has forced us to change plans, and that is unfortunate. However, we are committed to holding an alternate event in late July as well as supporting some other initiatives that our allies and fellow ex-gays are planning for July.”

Christian conservative Family Research Council (FRC) launched 'ex-gay' groups Voice of the Voiceless and Equality and Justice For All earlier this month after the closure of Exodus International.

Minnesota Congresswoman Michele Bachmann, a Republican, had been invited to deliver the keynote address at the now-canceled reception. Also invited to speak were Heritage Foundation's Jim DeMint, Liberty Counsel's Mathew Staver, Bishop Harry Jackson and Kansas Rep. Tim Huelskamp.

Voice of the Voiceless also declared “September as the first annual Ex-Gay Awareness Month.”

“Ex-Gay Awareness Month in September will be a time to reflect on the discrimination and marginalization that former homosexuals and ex-gays experience in the public at large,” the group wrote.
