Sometimes passion guides our words but I think using words like terrorism and genocide in everyday arguments lessens the meaning of those words and can be offensive to some who have lived through true episodes or who have lost loved ones. I do like your Martin Luther quote and suspect we do not use that one often enough
I didn't use the word genocide nor would I, and my best friend is a Marine who just got home from his fourth tour in Afghanistan, but I do think the word terrorism is appropriate here. I am terrified of a debt default and the devastation it could unleash on good, innocent people all over the world, I really am. And I think a lot of people are. Using and manipulating people's fear to get what you want is kind of what terrorists do.
Love is the answer, I hope.
