Fortunately, at least from what I've seen, GaG are not taken seriously by any significant fraction of gay people in the U.S. When three or four of them demonstrated in front of the LGBTQ community center in Greenwich Village this summer during Pride, cops had to protect them from enraged gay people who wanted them and their vile accusations gone.
Their accusations about pedophilia, which extend even to gay people who support trans folks, are so extremist and delusional that the group are viewed as cranks and crackpots — by pretty much everybody except the extremist Right.
