Just wanted to further explain earlier comment. The Chareidi world has decided that the best and only suitable time for Yiddishkeit is in the 1700’s. That was the ideal time to be a Jew. So they take the approach that we should try to convince bochurim that we really are living in the 1700’s. We dress the same way as then, we avoid studying the science and math of today, we ignore the State of Israel as if it doesn’t exist. We give shiurim in Yiddish which was spoken then. They simply have not been able to come to grips that times have changed.
But many bochurim realize that we are no longer living in 1700’s and they have been given no guidance on how to deal with the issues of today. They are very confused.
The modern also do not have clear ideas on how to avoid the improper parts of today’s culture, and are all too willing to accept everything, rather than to discriminate. Neither the all or nothing approaches are correct. But nobody has really been able to define a livable and halachically correct path. In EY for example, all sports are avoided for the most part. So they have no secular studies in HS, no sports, no realistic prospects of a job, no army, no concerts. This is very hard for bochurim to deal with, when they see these things all around them.
At least in the USA, chareidim have some outlets, but in EY, the problem is much worse. However, in the USA, there are really no uniform rules for Chareidim. People pretty much do as they choose.
There really is a need for gedolim to make realistic rules and give guidance on how one is to live his life in the 21st century. Nobody really knows what is permissible for entertainment, and whether anybody should ever have any entertainment at all, or it is all bitul Torah. It seems like one should try to avoid it if one is able to, but if he is depressed or lonely, than it is a mitzvah to get cheered up. How does sports fit in with Yiddishkeit? Is it Hellenistic and anti-Torah, or is it necessary maintenance of a healthy body. If it is proper and necessary, then why do we not see gedolim playing ball?
There is really much confusion on many issues of how to live a Torah life in modern times, and we are not getting any clear guidance.
