Hello,
1. Only one of the biggest? Who are my competitors? LOL
2. That is your opinion. Obviously others disagree with you. (gasp)
3. I did not write that there is a machloket about singing in the Chareidi “camp”. I wrote that there are machlokets. Do you deny this?
4. You’re welcome.
5. Can you list the marei mekomot for Rav Moshe’s pesak regarding shaking hands with a woman? I remember learning one where he pointed out that Orthodox rabbanim in Germany shook hands with male and female congregants on Shabbat evenings and wished the “gut Shabbos”. He says that they were probably relying on it not being chibba. The botoom line is that it is good to be machmir as one might derive pleasure from the contact. This is less than an outright “assur”.
6. Why does there have to be uniformity within a “camp”. Is there party and coalition discipline in Halacha as in parliamentary systems?
7. While we are on the subject, learn Rav Kook’s essay “Massa HaMachanot” printed in “Maamarei HaRaya” where he decries the existence of camps (in his time there were only: chareidim and chofshiim) as preventing teshuva.
