Above ALL else the democrat party has evolved to stand for radical liberalism. Reality, principle, logic, rule of law, morality, decency, responsibility, human rights, religious rights..... NOTHING is above the advancement and implementation of progressive - liberal ideology.
Opposing viewpoints are quickly dismissed as radical and / or ignorant or some under handed evil plot, thus dismissed as unworthy of debate. The motive and wisdom of the altruistic progressive is to be reverently respected and NEVER questioned. To do so would be utter blasphemy! To actually ask them to explain their position or debate their position would obviously mean you are some type of disrespectful moron or worse an unsavory character driven by greed and selfishness. That being said, you have lost all credibility.... at least that is what liberals think.
