It is impossible for Liberals to produce output as if it were created by Conservatives. They don't share the same world view. In many cases they cannot even comprehend the Conservative position on issues because it doesn't fit within the framework of their understanding.
The only possible way to resolve this sort of bias issue is to allow the people who believe in an ideology to have direct access to the equipment necessary to reach the masses.
The system needs to be reformed in such a way as to allow the 40% of Americans who make up the conservative base of support to have equal freedom of speech to that of the Liberals who currently monopolize and control the system.
