What worth has my opinion? My opinion is only the word of a dirty-minded pornographer. You, who don't mind the pornography, can look past it and judge the value of my taste on its own merits. But others will not give me that much consideration, and seeing the pornography, will judge me by that quality alone.
I do not want to cater to this mindset, because I do not believe they have the right of it. However, I cannot simply ignore them, either, for some of them will be people I have need of influencing in the course of my life, and others will be difficult to identify as such until it is too late. And though I might lose my respect for someone that displays intolerance, the force of their judgment still stings.
Ultimately, in the mainstream social circle, a person who judges others on the basis of sexual perversion maintains his moral integrity, because tolerance is not so highly valued as sexual purity (which is not to say sexual abstinence, necessarily, but whatever is the socially-accepted model of sexuality). If nothing else, that is something around which I'd like to influence society to change, if I can.
That I find beauty and pleasure in depictions (sometimes explicit) of human sexuality does not in any way mar the quality of my ability to determine beauty and pleasure in life and the world around me.
