I hear crying over who started it. Like any prolonged conflict in history, that makes no difference. Your fretting is akin to asking if the Israelis or Palestinians struck first. What matters is steering towards the outcome you want. And being informed of which path we are heading down. So I tell you America is devolving into open partisan warfare on the other party. Not yet violence, but boycotting and segregation. An ending of coexistence.
No, you hear crying from people who are used to steam rolling others. It's that simple. When put to task, conservatives don't care about what they claim to care about, and simply accuse others of doing what they are, in reality, doing.
Conservatives spent centuries fighting over who's version of religion and theocracy was correct. Now, they largely leave each other alone and fight against people who disagree with them as a whole, people who want freedom FROM religion as well as freedom of religion.
What you see now is growing pains of a society shedding it's deeply religious background in exchange for what our country was actually founded on. Freedom for all.
And overall you might be right about where we're headed, and conservatives strangling America can shoulder the bulk of the responsibility for that.
