Unfortunately, we are up against more than just your average 'joe' with a delusional perspective of our Constitutional rights. In my opinion, such a textbook example may not even be a 'genuine' person- but, rather, part of a much larger effort to influence public opinion at a greater level by our government and the private agencies they pay to do their bidding. Let's be honest, that comment went beyond the average uninformed gun-scared citizen, there were conditioning elements involved (i.e. guns no longer needed since the 1960's).
The US Government is actively involved in contracting private companies to log into forums, websites, and social networking sites to do nothing all day but spout disinfo, misinfo, and effectively steer whole topics, discussions, and comment sections in a desired direction, as if people weren't already dumbed down enough. This sounds certifiably crazy, except for the fact that it's very real: link, link. What really bothers me is that I've been seeing this far too often, and I think we would all be pretty well amazed if we understood the full extent of how many sites have been, and still are being, effectively infiltrated and subverted.
I only say this because we are not just witnessing blatant ignorance anymore, instead, there appear to be far more deliberate attempts actively made by our government and contracted agencies to manipulate and direct public thought in ways which truly do not serve the best interests of it's people. Of course, it's always sold to the American public as if it's in our best interests, but I think we fully understand how this game works by now.
This is why - when I have the energy - I hammer the crap out of people who show up here on NES and post this kind of drivel.
There's an awful lot of people sitting on the sidelines reading this stuff who never comment. People who post crap like that guy posted need to be argued down - not necessarily shouted down. They can't just be ignored - because even if he isn't some government stooge - when they spout crap like that guy did - and don't get any pushback, they interpret that as acceptance.
