You could look at it two ways.
Yes, by doctrine or general interference they are meddling in people�s lives by banning the use of contraception as they assert that sex is for the sole purpose of reproduction. Thus if anyone is doing the horizontal lambada, it is only to have children.
This of course carries the inherent risk of people having unwanted pregnancies and all manner of STDs etc. But this is not the intent of the �ban� as the ban also includes abstention, that is, ok, if you don�t want to have children and you don�t want to get an itchy rash and/or life threatening illnesses that are transmitted through sex, then you simply don�t have sex.
The problem seems to arise in many nations where either they do want to have children but their partner may already be infected, or they are ignoring the second part of the Papal canon. Of course, it can also arise through sheer neglect and lack of compassion/personal responsibility as well as instances of rape.
Now before anyone goes all uppity, I am Catholic and think the blanket ban is abominable. And, I went to scouts and was never treated differently to anyone else. Well, except when I got a badge for needlework and flower arranging, but that�s something else.
