Daas Yochid,
And here lies the major problem, most of what is being labled as assur is not so clear cut so. If most poskim say assur (and it has to be from a halacha standpoint,not hashkafa)(e.g. Reb Moshe assured the eruv in brooklyn halachikly, there were chassidhe rebbe’s that assur an eruv hashkafakly) it is still most not all, therefore there is an opinion allowing it. Why would we then force a kid to stop and further antagonize them. If all a kid hears is assur, assur assur then where is the beauty in yidishkeit.
