> Your argument is the same as “Guns don’t kill people. People kill people”.

Sort of, the argument is more like "Computers don't kill people. People with computers kill people by starting revolutions, committing online crimes, etc. Also, people with computers do lots of non lethal and helpful stuff as well too."

Facebook and mass social media are like that computer. Lots of benefits, lots of detriments as well. Doesn't mean you should cancel the computer.
