We're playing with semantics here.
While Trump wants to rid society of undesirable elements (illegals/terrorists), which invokes elements of fascist supremacy, remember, these are ILLEGAL IMMIGRANTS. These are not citizens of various ethnic groups - Jews, Poles, the mentally handicapped, or physically disabled. These are illegals who have zero right to be in the country. Zero. They should all be deported. Only Liberals think they should stay and borders should be open. This is nonsense lovey-dovey crap.
Is Trump authoritarian? Yes, I believe so. His willingness to embrace NSA surveillance and expand it, deeply concerns me. However, the argument to target mosques can be made under the pretext of counter-terror investigation. Trump has territorial ambitions (take the Oil), and will probably fuck up Saudi Arabia. Destroying ISIS and commandeering Arabian oil fields makes strategic sense. Listen, these butt-fucking muzzies fund jihadis with oil money and run amok. If America goes in, fine. But let it be with Allies (Russia, France, Germany, UK, China), and share the wealth a bit. If Trump takes over shit and declares Iraq the 52nd State, yes, that could be problematic and come off as rather "nationalistic". I'm not saying give it all away. But if America goes in with Russia and China, let them have some shit too. Responsible powers divide up the oil and the towelheads can figure out a new way to make a living.
