This isn't really the site for people who want to create genuine social change in the world, other than through startups. The site guidelines say that what's on-topic is "anything that gratifies one's intellectual curiosity". Curiosity is more about
knowing things than
doing things. I think one implicit belief held by the folks who started this site is that if you
do want to challenge entrenched power structures, the best way to do that is to be very circumspect about who you tell that you're challenging power structures, because you can expect to have a strong negative reaction from the power structures themselves. (Peter Thiel describes startups as "a conspiracy to change the world".)
There are other sites on the web that are attempting to organize people for large-scale social change, ones that are presumably watched (and cared about) by the FBI, as opposed to just being watched (with idle curiosity) by the FBI.
