I agree with HaKatan. They are presenting a valid concern albeit through a means that you are uncomfortable with. I don’t think it is right to label them zealots because of the negative connotation of that word, although I do believe they are being zealous in their desire to keep the klal in the Beis Medrish. That’s not a bad thing. If no one would remind us where we are supposed to be, eventually we will forget.
To you they may appear uncivilized in their manner of protest. Unfortunately, the atmosphere in E”Y is such that this is the only way to really be heard by a community that doesn’t use media. But make no mistake, they are providing a service for the all of us.
