I see a lot of similar comments, but I liked yours so I'll address the themes here.
First, facebook is not the only problem. You're kidding yourself if you think it is. The list of technology companies that sucker their users are as long as the list of technology companies that sell 'the cloud'. Google, Yahoo, Microsoft etc.
Worse than this, the evil is not marketing. The real evil is the secret pact between the tech companies and the government's monopoly on the initiation of force, for the benefit of a minority of oligarch families. The elite's technology branch
The real evil is the patriot act, the capture of government, the capture of industry and the subversion of the constitution. All tech companies are a part of this, most willingly, some unwillingly or unwittingly and the only honest ones are forced to shut down.
The capture of the government and industry is nothing new, but it reached tremendous success in the 20th century. First they captured the congress and the judicial, then the executive, then the monetary system and then they really captured the executive with the JFK assassination. Don't forget where some of the recent oligarchs originated.
- Are you against marketing?
- are you for privacy?
- are you for honesty as a virtue?
- are you for Free Software?
- are you for the constitution?
- do you believe in free will? (or that you should act as if it exists)
- do you believe in the traditional family?
- are you religious?
- are you for sound money?
- are you an Austrian or a keynesian?
- do you believe that there really is a 2 party system in the USA?
Do you see it yet? if you rule out the vast majority of the population based on internet usage, you're out of whack. Firstly because that's not the real problem.
Also, you might have MUCH MORE in common with someone who uises fb daily than on someone who doesn't, based on your OTHER principles and virtues.
It's like saying, "I'll only hang out with people who are atheists.". That's not enough. In 10 years time that could still be all you have in common. Or they could change their minds.
Finally I would just like to remind people that not only is the USA responsible for millions of deaths around the world, it now tortures people.
If you refuse to interact with people who support these acts, how will you ever change their minds?
Oh and just for good measure. A fucking surveillance blimp. The internet of things is coming to spy on you from the sky 24/7. Is it not enough that you've captured the mass media?
If you were to only hang out with people who share all your principles or most important beliefs, you would not hang out with anyone.
Furthermore, having intelligent debate with people who disagree with you (and are virtuous enough to have an intelligent debate) is the only way that you can make any sort of real progress in self discovery and discovery of the universe. If your ideas an principles are not challenged, if you don't go back to first principles to figure what what's really important, if you don't re-assess your beliefs in the face of new evidence, you'll never improve.
