szb1 – I have seen “Charedi” defined as “a member of any of various Orthodox Jewish sects characterized by strict adherence to the traditional form of Jewish law and rejection of modern secular culture”. I think that description is fairly accurate. I’m not sure about the ‘traditional form’ part; I would sooner say ‘strict adherence to Jewish Law’.
I’m not sure what you mean by why in your post. If you explain your question, I’m sure the posters here will try their best to answer you.
BTW – Kudos to you for your religious advancement. Kol Hakavod! I very much respect people like you who can pick themselves up from whatever state they find themselves in and strive to become better people, and to develop themselves spiritually. I wish I could be as strong as you.
