The biggest fallacy that I see Trumpers making is this argument that people are only opposed to Trump and his policies because of the media.
Sorry, Trump & Co, but it is YOU and what YOU are saying that America is opposed to.
The underpinnings of the Trumpism illogic appear to be founded on a single lie, which is that the differences between the right and left sides of the the political spectrum are based on economic philosophies, ie right wing is capitalism and left wing is socialism. This is false. There are right wing socialists (aka fascists) and left wing capitalists (aka anarchists). The actual differences between right and left are based upon the arguments between social hierarchy and social equality, respectively.
Now, with that in mind, the Trumpian deception becomes clearer. Belief in political hierarchy allows that politics be a kind of team sport, and that the 'team' in power has greater rights and privileges (ie 'you lost, get over it'). Rights are now no longer inherent, but bestowed by government ('only American citizens are protected by the Constitution'). And finally, the belief that anyone not for us must be against us, which leads to all the Trumpian conspiracy theories about 'the lying media' and 'the regressive authoritarian left,' which they are using in order to claim that the media and the left does not have the right to speak freely against the government (Trump).
These are interesting times. The people that America has traditionally relied upon to defend the sacred traditions of our Republic (conservatives) have been subverted into tearing them down. The threat to freedom is so great, they have been led to believe, that we can no longer afford to free.
