Confessions of a Cooperator
Hmmm. Well, If your point about being less puritanical when talking about sex means that we need to emphasize the beauty of sexuality and not treat it as something to be hushed up or embarrassed about, then I would agree but I'm not sure that throwing masturbation up on the parish web site is where we want to be. I don't think I'd want to hear about it in a homily either. It seems contrary to para 124 of The Truth and Meaning of Human Sexuality. I have to agree that the likelihood that kids are surfing to the parish web site is probably low but I still don't fault parents for being upset by what they saw. It also weakens the arguments against sex ed in schools since one of the reasons for opposing it is that parents have the right and responsibility to decide what information is appropriate for their children. If the parish is going to make that decision, then one could argue that the school can also.
You make a good point. In another forum, a response to Steve's article was that all publishers target certain markets, and an author should not complain if he/she is not published because the piece in question falls outside of the publisher's market. If this web publisher specifically targeted parish web sites, I suppose you could argue that its content shouldn't stray too far from what the parish site itself would contain. And parish sites, in general, do not stray far from what a parish bulletin contains.
Besides the sex angle, I liked the caution that Catholic web publishers ought to make sure they aren't sacrificing depth in order to gain a high hit count. I can't say that's what happened in this case, because it's author vs. publisher. But it's good for all of us bloggers to remember that we don't want to go after readers at the expense of truth.
Or maybe it's just me that needs to remember this! 
As a publisher we run into this problem too, and occasionally--not often--get letters from concerned parents that are a bit extreme. For example, one home-schooling mother complained about an incident recounted in a book we published on the life of St. Padre Pio. It was intended for older children and teens. The offensive part had to do with a story in which a woman confessed she had been unfaithful to her husband. It didn't even mention the word "sex." The story made an important point because it brought out the need for true repentance in order to be forgiven; that's why it was there. But this mother objected to it. I can only wonder what her children will do when they go out and happen to see a newspaper where they'll find a lot worse than that just in the ads.
