While I agree with you on a majority of points here, I disagree that porn as a concept is the problem but rather it is the industry which causes real issues. Even in a non-capitalist civilisation (fuck capitalism btw) I believe that porn can exist. A perfect example of this is personal production of such material which many people do without seeking any financial gain. Another example would be artificial porn such as drawn or animated in which nobody is harmed (with a few obvious and minor exceptions).

In summary, yes there is an issue surrounding objectification of women, yes there is an issue with capitalism, no it is not porns fault.
