Everything I've seen suggests that porn is pretty socially debilitating, especially for the current generation which has grown up with almost ubiquitous access to it (see for example http://www.internetsafety101.org/upload/file/Social%20Costs%...).

The report you linked to was produced by the Hoover Institution and the Witherspoon Institute. Do you have any reports that weren't produced by gay-hating Christianist organizations? Thanks.
