The first step to healing is to quit hurting ourselves - i.e. STOP voting for Democrats and Republicans. That strategy is a proven failure.
I repeat voting no longer works. It hasn't worked for 150 years.
Don't you see how ridiculous your premise is?
If voting didn't work and hadn't worked for some 150 years or so (which oddly enough takes us back to the year Abraham Lincoln took office), at SOME point, people would have resorted to "other methods," wouldn't they?
But I guess the South DID resort to other methods, didn't they? In the name of States Rights (which just so happens to be a conservative mantra these days), the South decided to break away from the Union and launched an unprovoked attack on Fort Sumter. The resulting conflagration ended up costing some 600,000 Americans their lives.
Are you suggesting that it might be time for a second bite at that apple?
