What happened in Orlando was horrific. It was also, very sadly, predictable, in hindsight. We have a young man, who, due to the confusion and lies of the sexual revolution, experiments with homosexuality and same sex attraction. He's also Islamic by family, and in keeping with being Islamic, is heterosexually married. In addition, over many visits to this gay bar, he keeps getting rejected by the gay men there, because, as we all know, homosexuality is based on abuse of beauty and youth, and he was no longer beautiful or young.
Add to that ISIS, a radical mosque that should have been investigated, but wasn't due to White House intervention in the FBI, and you have a recipie for disaster.
Multiculturalism is a mistake. It cannot be accomplished. The result will always be violence.
