Twisted –
Obviously, we can not rely on chitzoniyus, and presentation is no substitute for introspection and self-improvement. The Torah value in all of this is of course as a complement to, not as a surrogate for, “chovos halevavos.”
It is the sad truth that there are some for whom our community is no more than a social club; had these people been born in different circumstances they most likely would live largely the same lives in different clothing. Don’t let these people get you down on the community in general.
