Evander Holyfield's rant against homosexuality pissed off the former "Big Brother" star who once cornered the market on homophobic comments -- Aaryn Gries ... who tells us the boxer is an idiot.

Gries may have called a gay guy "queer" -- and true enough she mocked African Americans and Asians -- but Aaryn says her comments pale in comparison to what Evander said on "Celebrity BB" ... claiming homosexuality is like a physical handicap which can be cured by a doctor.

Aaryn says, "I know I said mean things, but at least I'm not ignorant enough to think that homosexuality is treatable. Seeing homosexuality as a sickness is outdated."
