How many bodies are under your floorboards? John Wayne GAYcy much?
Serial killers like John Wayne Gacy may be either gay or straight and what is more their sexual preferences have almost nothing to do with their sickness. He was also "Pogo the Clown" or "Patches the Clown" who performed as a clown at charitable events and children’s parties. Fear of clowns anyone?
Assuming you are straight, I could counter with Dennis Rader much? He murdered more than 30 women in seven states over a two-decade period. He told his wife and other family members that the smell in their home was caused by moisture.
What about Charles Manson, leader of the Manson Family, a cult of serial killers whose members committed a series of nine murders at four locations. Doctor Harold Shipman GP was found guilty of murdering fifteen patients under his care. He murdered mostly seniors... hmm, I have an appointment for an annual physical in July with my primary care physician, should I be worried? Let us not forget Ted Bundy (assumed straight) who killed more than 25 girls and young women between 1974 and 1978.
I could list a lot more serial killers who as far as anyone knows were straight. This begs the question, what was your point and was it valid or were you just being funny... like a clown?
