Why do Liberals bash anyone that disagrees with them?

In all seriousness do liberals have any cl they go all out with bashing the tea party calling them racists and bigots and don't get me started on how much they bashed Sarah Palin what ever happened freedom of speech if we say anything against the liberals we are called racists and what not. you bashed Bush for 8 years and we say one negative thing about obama and you are all defensive about it and out comes the name calling is this just a huge case of liberal hypocrisy?
