Excellent point, perhaps the larger issue might be that porn is more prevalent in today's day and age:

What made me roll my eyes while flipping through the presentation was the "in your face" attitude of inserting the images in the presentation to make a point. To me, the imagery exuded a certain lack of self confidence, but then again - big f'ing deal...it's not how I would get my point across. I see the insertion of the images as being a poor design choice and something that is not reflective of the larger community as a whole.
