Fundamentalist Christian group American Family Association is urging members not to accept any mail postmarked with the U.S. Postal Service’s newly released Harvey Milk stamp, the first U.S. stamp to feature an openly gay elected official.

“Honoring predator Harvey Milk on a U.S. postage stamp is disturbing to say the least. Harvey Milk was a very disreputable man and used his charm and power to prey on young boys with emotional problems and drug addiction,” an AFA press release said Wednesday. “He is the last person we should be featuring on a stamp.”

As one of the first openly gay elected officials in the United States, Milk’s efforts to advance LGBT rights earned him the Medal of Freedom posthumously from President Barack Obama in 2009. The 2008 Academy Award-winning biopic "Milk” was also inspired by the icon.

The AFA, however, viewed the historic commemorative stamp as a way for “the radical homosexual lobby” to “undoubtedly encourage businesses to use these stamps -- all in the name of inclusiveness, political correctness and diversity.”

“This is not diversity; this is perversity,” the release concluded.

The AFA, which has been listed as a hate group by the Southern Poverty Law Center since 2010, advised anyone who receives mail with a Harvey Milk stamp to take the following actions:

1. Refuse to accept the Harvey Milk stamp if offered by your local post office. Instead, ask for a stamp of the United States flag.
2. Refuse to accept mail at your home or business if it is postmarked with the Harvey Milk stamp. Simply write "Return to Sender" on the envelope and tell your postman you won't accept it.
