I'd choose to act gay, but be straight. Because people would eventually figure out you're straight, and then you wouldn't be a victim of hate crime, job descrimination, and prejudice.
Plus, if you're a man, you're at a much, much lower risk for HIV if you're straight, partly because of demographics, and partly because of anatomy. I say this not to imply anything about homosexuality; just that straight men should count their lucky stars that they don't have to worry about it as much. If you want to date a black gay man in America, there's a 1 in 4 shot he has HIV. Imagine thinking every 4th girl I date has AIDS, and she probably doesn't know it. Terrifying.
Okay, would you rather--
Live a life believing God hates you and hating the world for it, and end up going to heaven after you die.
or
Live your life thinking God loves you and loving the world for it, but ceasing to exist after your death.
