The last time I had lunch with my buddy I asked him if looking at these sorts of things combined with my interest in guns would get me put on a list. He said no. He told me it was more likely for his agency to receive a tip from a site adminsitrator of a website or from some other online service pointing out suspicious activity. Then they would assign someone to investigate and see if the person needed to be watched further. He said that in my case as soon as I was able to show any investigator some full length novels with information from the websites I had visited that most likely any investigation would end.
So, to get off a list, you had better have written a full-length novel? What if you just use the information to write a blog post? No, wait. Blogging is more "evidence" of right-wing extremism.
My brain hurts.
