As long as porn is stuff between consenting adults I don't really care. I don't want to watch bestiality or shitting DVDs because frankly it would disgust me and not arouse me at all but that doesn't mean I would in effect boycott a store because they carry this type of product.
I would draw the line at kiddie porn, which is illegal anyway and at DVDs depicting violent rape in a very realistic fashion (i.e. not "make believe" rape scenes).
