Believe it or not but we need things like beastiality, cp, scat, etc. in order for the industry to survive. I know it sounds fucked up but it is true from a logic standpoint.
There will always be an extreme left and an extreme right viewpoint. The extreme right will always fight the extreme left and vice versa. That is the nature of things. Now, lets say that all of a sudden, there was no more beastiality, cp, scat, etc. Guess who would be the extreme left then? Look at it like a straight line with the right end being the moral police and the left end being the immoral degenerates. In the middle is the average joe. Each section of the line represents a level of pornographic acceptance as you progress left or right. If you eradicate one end of the line (like the extreme left end) it only makes the next level of pornographic acceptance the extreme left and moves the middle (or average joe) over to the right. Then the extreme right will fight the new extreme left. It is a matter of sociological dichotomy.
Whether you agree with the extreme left is not important. If you fight the extreme left then you are aiding the extreme right and eventually moving yourself towards fighting the left yourself.
Now where the fuck did I put my beer?
