smartcookie, actually bakeries are not needed for daily living. I can cook bread in my own home easily. Bakeries are a luxury. Facebook is the cheapest and easiest way to communicate with lots of people (especially photos/videos of family and friends) and can be just as much a “neccesity” to some people for communications that otherwise they couldnt afford (like communicating to Israel) as bread or cookies from a bakery.
I have no problem with people NOT being on facebook, but I do have a problem with people saying facebook is assur and things like that. It is NOT assur. If you are sensitive to it, dont use it! Just as an alcoholic avoids alcohol, people who cannot control themselves properly SHOULD NOT USE FACEBOOK. But that doesnt mean I support the Prohibition.
