I'm not anti-gay, but Harry Hays was a known gay activist for NAMBLA (North American Man Boy Love Association). I'm pretty sure any organization he helped found, or was a part of, is very likely to be an off shoot of NAMBLA.

In 1950 Harry Hays was the founder of a group called the Mattachine Society.

THE MATTACHINE SOCIETY OF WASHINGTON D.C., WAS FORMED IN 2011!
