(a) I'm not saying anyone in particular here does that - although a number of you support the practice rabidly. By supporting the rights of others to do the same, you are sharing the responsibility.
(b) No, I do not engage in either of those practices, JFYI.
I am speaking about the cultural acceptance* (and forced legal acceptance) of all-pervasive pornography. If men don't masturbate while watching porn, why do those "adult" movie shops offer private booths?
No, I've never been in one. But anyone can see them as they drive or walk around towns.
*Although it would be very interesting to find out what percentage of a given population - the country as a whole, particular states or communities - want the continued legalization of porn, and what percentage want to see some restrictions.
