There are people, including some who wear a certain type of kippa, who benefit from nuts like these making the rest of us look bad.
Some of them pay these nuts or otherwise egg them on, and others go to the press or spend inordinate amounts of time discussing these nuts, giving them the attention they want and that they are paid to get.
They are nut kases, and their cause is strictly to get attention. One of their ilk outside EY left NK and decided to get back into the news by forcing a girls’ school (of the Chassidish Beis Yaakov sort) in Antwerp to accept his SONS!
Ignoring them will make them go away. Even having them arrested will only encourage their mishegoss. They will never be punished for what they do as long as certain parties benefit from using them to tar all charedim with the same brush.
