What you said — PLUS:

There is a documentary titled "This Film Is Not Yet Rated" (2006).
• http://www.imdb.com/title/tt0493459/
It details the secretive processes and often homophobic attitudes of the ratings committee and the entire board.

If you decide to see this documentary, be prepared to be incensed — and I mean steam-from-the-ears, flames-from-the-eyes infuriated.

One of the things the documentary did was to show side-by-side clips of various scenes of similar activity; a straight couple kissing, a gay couple kissing; a straight couple in bed together (not having sex), a gay couple doing the same; etc, etc, (get it?). The film with the gay couple always got a rating at least one degree worse than the film with the straight couple.

The filmmakers also did some detective work and documented a number of homophobic inconsistencies in the policies and practices of the MPAA — and some outright lies in their claims of equity and of the composition of their ratings personnel*. The filmmakers further describe the board's secrecy almost to the level of paranoia — "to protect the panel members." They also describe the "appeals" procedure. You'd have more rights facing a drumhead court-martial. At least then you would have the right:
• to know the specific charges against you (or your film)
• to know who had participated in the original decision
• to know who was participating in this decision
• to present precedents where similar situations had resulted in a different decision.

*Among other things, the MPAA claims that their ratings board is made up of parents of young children. [BUZZ!] WRONG! The filmmakers detective work found that only one of the 6 members was the parent of a minor child; another member had no children at all and the other four had children in their 20s and 30s.

And yes: A film can squeak by with a 'PG-13' rating if it has only one use of the 'f'-word — if it has no LGBT characters.
