That's not strictly speaking politicians, though, that's directly due to pressure (often exerted transparently) from interest groups, and much of it is completely reasonable (for example, calling someone a nigger in the street will get a person arrested). I understand your perception, I just think that much of the time, that attitude is a reification of media stories.
