@Mother in Israel: It’s very commendable that you and your husband sensor what your children read. But, since no man is an island and we live in a community where people run their homes the way they see fit, might I suggest that you explain to your children if they ask, that everyone runs their home according to how they see fit. What may be acceptable in their homes is not acceptable in yours.
Your children walk in the street to school, shule, friends homes and they pass newspaper stands and see all kinds of magazine covers. You can only shelter your kids so much. Sooner or later kids see and hear everything.
It is not appropriate or acceptable to “stash” your hosts’ catalogues/magazines. I personally would be offended if a guest would ask me to “hide” reading material in my own home. If you don’t like what they do, don’t visit. You can always meet in a neutral spot like a pizza parlor or the mall.
