Americans are taught to avoid political ANALYSIS at all costs. They recoil from it like it was a snake or scorpion. It's taught from kindergarten, using the desire to have fake harmony and group cohesion.
When that teaching goes awry, you get this type of intolerant ranting against the Other.
Thank you, liberal educationists. Every child a winner, all dissidents go sit in the corner. Align culture with our nature.
That is okay: There are folks to do your thinking for you. That is where the corporations come in.
I do not say this on my own surmise. The Exile has been following the Tea Party from the outset. The case they make is that it is astroturf. (Astroturf, which literally is artificial grass, refers to seemingly popular movements that are actually centrally organized or funded. In the US it is certainly the new way of doing politics, and cuts out the messiness of actual popular movements.)
I know of nothing that gainsays their analysis. The Fates are kind.
