Before you lot start disseminating your da’as hedyot (no offense), let’s get clear the da’as Torah.
For more info as well as a beautiful explanation and appreciation of the value and importance of tzenius, see sefer Oz V’hadar Levushah, in English, by HRH”G Rav Falk SHLIT”A from Gateshead, England, with whom I am zoche to have a strong kesher.
There are two ‘dinim’ here, the first of which I hope is irrelevant to all of us; to protect ourselves from being influenced by the conduct of parutzim/os who are beyond the point of no return. In the times of the Sanhedrin, someone who did a serious aveirah in this field was thrown off a building / cliff, or had molten lead poured down their throats, etc. – uvi’arta hara mikirbecha. Now, of course, this mode of enforcement of that which is correct, is wrong, as is any other violent punishment, as we don’t unfortunately have a sanhedrin of mumchin. But the concept of taking extreme measures under the guidance of da’as Torah to ensure no breach of tzenius standards is certainly there.
To take any steps in this direction, however, without the clear directives of da’as Torah is, as the outbursts in Beit Shemesh about a year ago showed, destructive at best and suicidal both physically and spiritually at worst, as the non-conformists will davka be more peritzosdik just to get back.
The second din is to try to be mekarev those members of Klal Yisrael who have unfortunately fallen through, and try to bring them back through education and love and genuine appreciation of who they are and their status as children of HKB”H. Great care must be taken by those who embark on this route so as to not expose themselves to more than is justifiable, and da’as Torah, as ever, must be sought in each individual case, as each case must be judged on its own merits.
The bottom line is, the current situation is far from ideal, and da’as Torah must be sought to find out which practical steps, if any, should be taken, and which form those steps should take.
