The notion that Democracy is the ideal form of government is neither supported by history or the Western Philosophical tradition, yet we believe it to be and are taught history in an inaccurate manner so as to uphold that narrative. We engage in foreign conquest, violence, and oppression under the banner of "spreading Democracy". We categorize all human societies as "good" or "bad" based on their adherence to its principals, even though we do a questionable job of adhering to those principals ourselves. We have impassioned debates and physical conflict over the "proper" interpretation of it, and who is, in essence, the "most loyal" to its ideals. Questioning the merits of it in public will result in social ostracism, and possibly even detainment. Questioning it's merits will generally result in accusations meant to completely discredit the questioner (Nazi, Communist, etc..) There's plenty more parallels, I'm sure.
