You're absolutely right in my opinion. I am not a hard-core liberal by any stretch, but I'll admit to being left-leaning. I firmly believe in the right to bear arms for many of the same reasons your average right-winger does. A: We have a right to protect ourselves (especially our homes). How does that old saying go? "When seconds count, the police are MINUTES away". And B: I don't trust the government any more than a lot of the so-called "paranoid right-wing nuts". In recent times, I've seen our rights dwindle more and more (over the last 30 years especially). Most of the time it's under the guise of "public safety" (like the post 911 "Patriot" Act and the assault weapons ban that was based on public massacres). I do have to pose one question in regard to the public massacres though... What are WE doing as a society that is driving more and more people to these despicable acts? It seems to me like the heat has really been turned up in American society in regard to pressure to survive and succeed, yet little to nothing is really being offered in terms of coping skills for people who are buckling under this ever-increasing pressure. We live in a psychic pressure cooker, yet we have essentially NO mental health system in our country. There are mental health services available to some, but they require private insurance and are hence inaccessible to a lot of people. We live in a perfect storm for these types of outbursts. I expect to see a lot more of them as time goes on and population increases.
I guess I would pretty much agree with everything you said here and I'm no left-leaning liberal. But, I too agree that rights have dwindled over the past thirty years for any number of excuses under the guise of "public safety." But this is the reason for paranoia. It's hard to know who to trust anymore when you watch your government take away your right to live by your own choices instead of theirs - and I do mean - as long as it harms no one else or interferes with their choices or way of life.
Some times I wonder if the movies made today with all the killing, torture and realistic bloodshed has an affect on young impressionable minds. Some are convinced video games contribute to irrational or brutal behavior by desensitizing the young mind. But millions of kids play those games and realize it's just fantasy. It's the mentally unstable, IMO, that go over the cliff and act out the fantasy.
Like you, I also expect to see a lot more of this in the years to come.
