A means for the illiterate to acquire political opinions.
Talk radio operates on the philosophy that a person should choose a side in political debates (usually either 'staunchly liberal' or 'staunchly conservative'), then incorporate that side into their
personal identity. This frees them of the need to submit to bothersome processes like thinking for themselves.
Talk show enthusiasts can be identified by their
dogmatism and easily excited sense of self-righteoous indignation.
