All of politics is a bunch of ecochambers with some rare meetings and debates between the opposition happening sometimes. People, who are claiming, that they've reached some sort of complete consensus/equality, have either met a submissive person (when speaking of personal relationships) or are the one-party systems (when speaking of the global politics) - and everybody knows what that entails.

Truths are objective (though may be incomplete/manipulated), common sense is a relative interpretation of the truths.
