The truth is that Jehovah's Witnesses purposely try to insulate their own members. They want their own to be "no part of the world". They do not sanction unnecessary association with "worldly people". Even certain Witnesses within their congregations are viewed as 'weak ones" and some are even 'marked"to be taken special notice of (due to their not adhering to counsel and direction from their elders).
Children are raised to stay away from non-jw kids, They are told to not engage in interactive sports after school or clubs because they must remain "unspotted" by those that are not Jehovah's Witnesses. Going to college is considered a terrible choice and if an elder desires that his child goes to a university, the others in the congregation will view him as someone they can no longer respect!
Many people think Jehovah's Witnesses are weird, different, odd. And they are. They want to isolate their members and have them depend upon no one in the outside world.
JEHOVAH'S WITNESSES ARE A CULT!
