A witness testifying before a Minnesota House panel considering a gay marriage bill warned that legalizing such unions would lead to “ejaculation inside of a colon.”

Mike Frey, who introduced himself as a “concerned father and husband,” spoke before the House Civil Law Committee considering the proposed marriage law on Tuesday.

“When ejaculation occurs inside of a colon, it's highly absorbent material, the cells [unlike those found in a vagina] do not have a barrier for the sperm and those enzymes to enter into the blood flow,” Frey explained. “When the enzymes enter into the blood flow, and a continued, prolonged environment of that happens, these enzymes in the blood flow, it causes what we know as AIDS.”

“And AIDS, of course, brings on common diseases, colds and things, and it magnifies them to a point where it's unhealthy.”

“I urge you to vote against the changes inside this bill because it's going to put a health risk to the society at large and it's going to put a financial burden on the people of Minnesota to be able to support all of the diseases that will come out of this.” (The video is embedded on this page.

Writing at The Huffington Post, Cavan Sieczkowski called Frey's testimony “homophobic” and “misleading.”

Sieczkowski reminded readers that more than half of the 34 million adults living with HIV/AIDS globally are women and that it is simply not true that women's bodies can somehow block transmission of the virus.
