You vehemently disagree that the environment has changed or you just couldn’t care less as it doesn’t impinge on your lifestyle?
I’m not Jothar, but I disagree that just because people aren’t associated with BMG or following certain “standards” (especially non-halachic ones), that the newcomers are on any less of a madreiga. Just because you learn full time in BMG and have been there for 20 years, doesn’t automatically make you a chashuv person. You may be, but its not automatic. And you may be no better (or even worse) than the man who moved to Lakewood and goes to work every day. That isn’t your cheshbon to make.
I would compare what is happening to Lakewood to what happened in Monsey. Monsey started as a town based a lot around Bais Medrash Elyon and then flourished from there. While Monsey has many problems, it now hosts many frum Jews all over the spectrum. Learning to live in harmony with people with different hashkafas is not always easy, and sometimes causes isolation. But no group is really better.
