There is no such thing as a Chiloni COMMUNITY, there are Chilonim, but they are not associated with each other in any other way.
Unlike the Charedi community where you might say the Satmar, Belz or Yerushalmi community. When someone says they are Satmar they are saying they are part of the satmar community, when someone says they are Chiloni they are simply saying they are not religious.
The charedi want to be seen as a community, and when they look good , it works for them, but when one charedi does something wrong, it looks bad on the entire community.
