DY,
In general, in Chinuch you have to strike a balance. Sometimes, its better to expose your kids moderately then have them exposed some other way. Knowledge is power and that’s different for every child. Some children do better totally isolated. Some do worse.
Mod80, I’ve been to plenty of bars and was not surrounded by debauchery. Its a matter of knowing which ones and going at the right (or “wrong” LOL) times. My office does Happy Hour rather frequently and let me tell you that at 5 pm, most bars are filled with men and women in their business suits having a beer or two.
