Lil' Scrappy -- Closeted Gays Spread AIDS

Rapper Lil Scrappy believes gay men like Frank Ocean are the "doorway to AIDS" ... and wants more closeted homosexuals to "come out" so it can't be spread to straight people.

Scrappy -- who now stars on VH1's "Love & Hip Hop: Atlanta" -- was on "TMZ Live" this week to talk about Ocean's revelation ... when he explained why he completely SUPPORTS the R&B singer.

"I'm glad that he came out ... so all the real women that love to mess with real men, straight men, we can keep the AIDS situation down, you feel me?"

Scrappy continued, "[homosexuality] is a doorway to AIDS, scientifically."

As for the facts, there is evidence that shows men who have sex with men are at an increased risk of contracting HIV. According to the Center for Disease Control and Prevention, men who have sex with men accounted for 61% of all new HIV infections in 2009.
