I don't like the man nor what he's done to this country or the effect he's had on the world, for that matter, but I just don't accept any of the claims of anything I saw in the video or in any of the related videos. They seem to come from a bunch of homophobes, bigots, racists, and nothing is substantiated by any facts. All speculation, appearances and accusations.
Because he's an elected official, people who make statements like those are essentially immune to prosecution, and that seems to encourage some to make unfounded accusations. Were he and his family not public figures, the accusers might be in for some hefty fines and jail time.
