Richard Dreyfus is just talking common sense. Or, more accurately, sense, as it doesn't seem to be common these days, especially in Hollywood.

I wish these people would get it through their thick skulls and into their tiny brains that diversity in and of itself, whilst laudable, is not indicative of a film's quality, and that regulations of this kind are a creative straitjacket.

I once had a conversation with someone who tried to convince me Lawrence of Arabia was a bad film because it failed the Bechdel test. It wasn't a long conversation. Given the near-religious experience I had when first viewing that film in the cinema (the gorgeous 70mm 1989 restoration print), I simply pitied them and walked away.
