Unfortunately we are in a bad situation in the liberal run areas. If we fight back we will be blamed.
To be clear I do think we should fight back. In fact I remember back in the early 80s when the situation was worse than today there was a major fight in my Brooklyn neighborhood. A then (niftar long ago) member of the Moetzas Gedolay H’Torah told people afterwards that they should have called the JDL . On Shabbos. And despite that gadol’s personal general vehement opposition to the JDL. (Had the JDL limited itself exclusively to self defense he would not have opposed them) The Chaptzems were also a very effective crime fighter.
But that was then when the police were apathetic towards fighting crime but didn’t arrest those who did so themselves.
Today when guilt and punishments are determined by skin color, frum people are considered guilty until proven innocent it’s not so simple to fight back without making the situation worse.
