Homosexual Agenda for Dummies

I've been reading a lot about the alleged "homosexual agenda"  by gay people and just saw how this wonderful Pastor John was trolled out of existence for writing about it. What a wonderful "Christian" he is. I'll take our cool Pastor Dan any day (and I'm warming to Mrs. Pastor, but she gets cranky on occasion)

Anywho, can someone give me some short summary of what this alleged plot of us gay people is so I can understand? (Please, please say it somehow involves me having sex with Jude Law.) Seriously, what is the argument made - that we are a danger to society by just existing or that we are a danger because we are not sent off to camps? I'm confused - splain to me.
