There is definitely a niche for "intellectual porn" and people doing that successfully and making money off of it, but I would concur here that it is harder to get these people to pull out their wallets. Because they tend to be more intellectual in just about everything, not just their porn.
My suggestion would be that if you are going to market to this niche, and make no mistake, "socially conscious intellectual porn" is a niche, not mainstream, that you load up you sites with stuff they will actually pull out their wallets for, quality and unique sex toys, retro porn sites with real retro content, perhaps a quality dating service, unique cam niches -- those are the things that sell good on one of the sites I do that's within the niche you are talking about. And good luck!
