I saw a link to the following bulletin board Lockers.Net and I was absolutely blown away. I went to a co-ed day school and a so called "modern" high school not that long ago and after reading some of the entries would never dream of sending my kids to a school like that.
In truth, I don't understand how anyone can advocate co-ed schools, camps, etc. It creates tremendous problems (just read some of the posts).
The kids in that forum are frum in name only, they have no idea what it means to be frum and no ever taught them, a very scary thought.
