I avoid this by not watching porn that makes me sad. There's plenty of consensual, happy, joyful sex-positive porn out there.

While your point is valid about this particular situation (which is horrible and criminal on multiple levels), your overbroad generalization of porn and the implied assumption of guilt in the viewers is what's led folks to react negatively to your statement.

On a larger level, this kind of statement plays into the puritanical doctrines towards sex that paint it as a negative force, and subsequently leads to the twisting of a positive, creative act into a negative expression of power and rape in those that accept those doctrines.

Porn is not at fault here, nor are its viewers. Those at fault in this crime are the producers and publishers, who were well aware of the abuses happening under their watch, and deceived their viewers into believing they were observing consensual performance acts. I hope that these women get every cent and more, and it would be excellent to see a class action suit from Pornhub's subscribers arise in tandem to and in support of their complaint.
