I didn't let her off the hook and maybe I misinterpreted your statement. But all to often we call lone white males "mentally ill" and anyone who doesn't fit that criteria a terrorist. If you weren't going there my apologies.
Seems to me we're all good, but I'm becoming more impatient of people picking terms which are defined with motive. Those guys who took and held federal land were terrorists by the definition of the law. The bombers in Boston likewise. This woman too. The bomber in Austin was not.
The difference is between motivations and causes the latter being dangerous because they can spread like a virus. We've seen it.
I didn't make a distinction because of anything other than the desire for a cause. Does that make the acts of the bomber less horrible? By no means! Is dying because someone wanted to have some fun and they slit your throat better? Again no, not at all.
But in RATIONAL discussions as to how to approach an event we need to undertand motivations and think how to approach them. Saying "get rid of guns" is all well and good, but trust me as neckbeard as it may sound. I can efficiently kill many people, more than this woman without a gun. No, if life is worthless, secondary to "the cause" or just because it's cheap where one lives, this nation will remain a violent and deadly place. Those that think not ought to look at the UK, particularly London. What happened? They are adopting the perspective of lives not being valued.
I support reasoned compromise. No one will get everything they want, but until we understand our natures, understand why we do things, tossing around words without understanding, protecting the favored, taking proper actions against the wrongdoers nothing will get better.
Be angry. Want justice, but don't lie to yourself or others about what things are. BTW this isn't "you", but us as a society.
