Being “anti-rock throwers” is akin to being “anti-graffiti vandalism”. Who isn’t that? EVERYONE is anti these things. Do you go around yelling what terrible people blacks are due to the graffiti vandalism they commit? Of course not! Their youth engaged in such vandalism are a small minority of their community and do not represent the community one iota. No one would dare criticize the black community due to the graffiti vandalism!
Yet, regarding the frum yidden — for some folks here — it is perfectly acceptable in their twisted thinking to criticize “chareidim” for what a very very small number of fellows do. Despite the fact that rabbonim where they live have repeatedly and severely critcized their misguided action. These small number of fellows — who represent no one and are an even smaller element of the frum community than the graffiti vandals are an element of their minority community — do not listen to any rabbis.
