"In a lengthy entry on Conservapedia, he writes that gay murders are 'relatively or quite common,' [...]"
Unless you can provide conclusive, peer-reviewed evidence showing otherwise, I am going to assume there are probably, proportionally speaking, no more or less LGBT murderers than straight murderers. (I honestly haven't looked up any statistics on this, because it's not my place to prove a negative, so I'm not going to make a claim either way; I don't like pulling lies out of my ass, unlike you and your ilk.)
"and gays are more likely to abuse drugs."
Again, no more or less than straight people, unless you can prove otherwise. If drug abuse is a greater problem among LGBT folk, it's very likely because the flack you give them drives them to it. It's a self-fulfilling prophecy. Tell people they're bunch of disgusting and worthless degenerates, and low and behold, some of them will act like it because hearing that shit makes them believe it and hate themselves.
"He says that’s merely a 'candid explanation of where the homosexual lifestyle leads.'"
More like a candid explanation of where homophobia and heterosexism leads. You have blood on your hands, Andy.
"The fact that his own brother, also a conservative activist, publicly came out as gay two decades ago changes none of this, Schlafly said: 'He’s seen it and he’s had no objections.'"
Sad, just sad.
"And his students have never broached the topic in class. 'I’ve never heard of a gay home schooler,' he says."
Even as a kid who was homeschooled for several years due to both bullying and being an army brat whose father was often re-stationed at that time, I still have to admit that most homeschoolers in the United Statesor "homskulers" as I call them in this particular casedo so because they can't indoctrinate their children with lies, fear, and hate.
