I think you and Kuvult envision different scenarios, both happening: you are talking about mixing with random people in a public or MO school, Kuvult seems to be talking to some special people with certain character that happen to be non- or less-observant.
I am not sure whether it was wise to have kids fully integrated even i the second scenario, but it is definitely wise to teach the kids that there are people with dignity and purpose that may not be wearing same hat as you.
