Msseeker: I’m ready to debate/discuss (however Sundays I’m not always available to respond).
Itchsrulik: Regarding your first issue: The value of isolation in the Chareidi community.
The Chareidim believe that physical separation from the secular world is a central point in Judaism. This concept has it’s origins from the Tena”ch and Gemara, as well as being the tradition of Klal Yisroel dating back to the times they accepted the Torah on Har Sinai.
1) The Possuk in Tehilim says: “Hein Am L’Vudud Yishkon U’Bagoyim Lo Yischashuv”, meaning that the Jewish nation dwells alone separated from all other nations of the world.
2) The Baal Hagaddah on Pesach states “Va’yihi Shum L’Goy”-Milamed Sh’huyu Yisroel Mitzuyanim Shum” meaning that the Jews guarded their physical separation from the Egyptians, as the Gemara explains that they wore unique clothes, had unique names, and spoke unique language. (The Mahar”l explains that for this merit they were redeemed from Egypt.)
3) The Gemara in Migilla explains that in the times of Mordechai and Esther, the reason why it was decreed from heaven that the Jews be destroyed from the world, was because “Nehenu M’Si’uduso Shel Achashveirosh” they participated in the banquet which Achashveirosh made. Not that they committed actual issurim there; but rather the mere participation alone was enough to cause on themselves the terrible decree.
So we see how the Torah stresses such importance for Jews to keep a physical barrier between themselves and the secular world. Charedim understand this concept of separation, that it is in order for Jews to internalize that they are a special nation who is connected to Hashem. If Jews would be integrated into Goyish society it would be very difficult for them to feel the truth of this central belief of Judaism that the Jewish people are indeed the chosen people by God to be forever unified with Him.
