The Shpoler Zaide had a chossid whose parnosoh was owning and tending a bar. He approached the Rebbe with a complaint. “I spend my day in the company of the customers, who are at various levels of intoxication, who are speaking about the worst subjects with the worst vocabulary. I feel this detracts from my Avodas Hashem.” The Shpoler Zaide responded, “So you prefer wearing the levush of a rebbe, sitting all day in a room full of seforim, and occupying your day with only Torah and davening? That is the Avodah of a Malach. HKB”H placed you where you are because he wants you to perform mitzvos in the environment where you are.”
It is one thing to bring on nisyonos. It is another to lock one’s children in a box. The latter, in the extreme, is quite dangerous. One will eventually emerge from that box and encounter the world. There will not be the needed immunity to withstand challenges, of which there will be plenty.
There is another reality. The yetzer horah takes no vacations. If it cannot expose our children to the schmutz of the world via internet and technology, he will simply find another way. There is an important aspect of סור מרע, where we give our best to block ourselves from exposure to toxicity. But equally as important is the עשה טוב, where we fill our space with kedusha that repels the influence of the yetzer horah. Sadly, we have reduced so much of our Avodas Hashem to perfunctory performances, theatrical shows, and efforts to impress others. I heard someone on Sukkos bemoaning the inability of leaving a price tag hanging from his esrog so that he could advertise to all how much he paid for it. For whom did he spend to fulfill the mitzvah?
No way is wrong or right. It is the matching of the derech to the individual, and the moderation that makes the difference. It becomes bullyish to dictate these details or standards for the public.
