Cities are probably relatively liberal -- or at least, cosmopolitan -- in most parts of the country compared to non-urban areas nearby, but that doesn't mean that New York City, Atlanta, Kansas City (either of them), and San Francisco are all equally so. It doesn't even mean that cities in some regions aren't far more conservative and/or intolerant than non-urban areas in other regions.
