"He has supported AIDS charities for years, and welcomed gay couples at his Palm Beach club when doing so was considered remarkable. And he has recently started insisting that he would be a better friend to the gay community than Mrs. Clinton, even though he opposes legal rights like marriage. But as he tries to convince social conservatives that he is not acting as a moderate, Mr. Trump has been largely hands-off with the platform.... The Republican platform committee has long been dominated by some of the party’s most stalwart activists. And some of them have hardly been shy about their views. There is Cynthia Dunbar of Virginia, who has compared the gay rights movement to Nazism. Hardy Billington, a committee member from Missouri, placed an ad in a local paper asserting that homosexuality kills people at two to three times the rate of smoking. And Mary Frances Forrester of North Carolina has claimed that the 'homosexual agenda is trying to change the course of Western civilization.'"
