“Some do and some dont, You are going to have to decide at some point which community you want to be a part of . If you are going to be part of the More Chassidish or Yeshivish communities then you will have to give up the TV. If you are going to be part of the more modern communities, you will not have to give up the TV”

Also, some communities contain different types of people.
