I didn't say any of that, I said people did not defend the Cuties movie like you are implying. Plus the left does not defend child trafficking or rape of minors. They criticized what they believed to be right propaganda. Whether you think its true or not its a different story. Making strawman arguments and generalization leads to tribalistic debates that go nowhere.
In addition to what ZNP said, I will say that by attacking what they perceived as RW propaganda -- and this movie in no way attacked political Leftism -- they inadvertently and/or deliberately defended child rape.
As for simplistically defining the culture war as tribalism, you show yourself to be thoroughly ignorant of what's going on. This is no longer merely about welfare policies vs. holding yourself by your own bootstraps. This has fully matured into a Marxist cultural revolution. The Left has forced the issue by going extreme, using the instruments of justice, media, and education to indoctrinate and punish its political opposition. The Chinese, Russian, Italian, German and Cuban people did
not become "tribal" as you say, and they fell to brutal authoritarianism.
I cannot believe someone can call himself a believer and not be appalled by what they see the Left doing. This is no longer "liberal" vs "conservative". This is communo-fascism vs. liberty.
The US Air Force recently threatened its members to not attend a conservative rally lest it damage their careers. Who's being divisive?
President Vegetable Head, a.k.a. the great uniter, called half the country dangerous to democracy. Who's being tribal?
Douglass Mackey makes an anti-Clinton meme, gets thrown in jail for 7 months. Katie Wong does precisely the same thing, and doesn't even get charged.
There are too many examples of the Left attacking the Right in America, and in other western countries as well. I won't even start with Canada's or New Zealand's governments.
We're being fired upon, but keep telling yourself that we're just as bad, or that it's merely fireworks.
