The TLDR of the situation is that you shouldn't worry about what the NSA flags you as. They flagged everyone. Just assume you're on their list because you probably are anyway.
The Snowden releases have done exactly that - in a perverse way, they make me take many more risks online. "Everything I do is already being tracked, so I might as well search for that new Daesh (IS) video."
No--Everyone is on the NSA's list, that is unjust, and I would encourage you to join others to work for justice by increasing the cost of suspicion-less surveillance through mutual aid and solidarity, like using the Tor Browser Bundle.
