How fast will humanity go extinct if the Gay Virus is allowed to spread via married couples now? Years? Months?

Instead of running the chance of one gay guy coughing on you, giving you AIDS, and then turning you gay; now you have two guys running the chance of giving you AIDS and making you gay all thanks to gay marriage. That almost doubles the chances of turning you gay now. And since gay people don't reproduce, we'll all be sterile in no time. Scary. FACT.
