I don't think we've hit that tipping point "yet." I still have hope that we never will. You're correct in that things have changed. What it took then and what it would take now are different animals.
I was making a specific point though, which you've highlighted, and which escaped a lot of other people, I think. The people who did what they did in 1776 would not stand for what our government is doing to/against us now. They fought for a LOT more than the garbage we're sucking down willingly now. Our government is completely off base and way outside the lines of what should be considered acceptable.
They're acting like the rotten kids who get caught with their hand in the cookie jar, and then throw themselves on the floor screaming in rage at their parents, because they hope their show of emotion will distract from the sin they just commited. We're being led by a pile of toddlers.
