... So this is a very confusing situation, and what makes it even worse
is, our standards keep changing. Take Playboy magazine. Back in the
1950s, when I started reading it strictly for the articles, Playboy was
considered just about the raciest thing around, even though all it ever
showed was women's breasts. Granted, any given one of these breasts
would have provided adequate shelter for a family of four, but the
overall effect was no more explicit than many publications we think
nothing of today, such as Sports Illustrated's Annual Nipples Poking
Through Swimsuits Issue.
