If it is true that US people fall into two broad tribes, the reds and blues, and the particular complex of characteristics that mark out one from the other are adopted by individuals primarily to signal their allegience to their respective tribe. So for example blues talk up bicycles because reds talk up muscle cars. Then I expect the red tribes current tendency to signal against Islam and Islamic terrorism to eventually manifest in the blue tribe wearing Osama T-shirts.

One notable characteristic of the Blue tribe is their tendency to signal an interest in communism which iconically manifests as the wearing of che t-shirts particularly when young. To understand the psychology of this you have to compare this to the red tribe who of course signal strongly against communism. One primary drivers of the red tribe is signaling its patriotism for america and its military establishment. During the cold war the US military establishment was overtly engaged in a hostile posture versus a number of rival powers that were at the time wearing communism as the official state ideology, that would be USSR and China chiefly but also Cuba and Vietnam. Consequent to this hostile posture the red tribe, to signal its patriotism, adopts a comparable attitude.

Please Help.
Thanks !

I didn't find the right solution from the internet.
