Step 1: I hate Trump because Trump is evil.
Step 2: Because Trump is evil his actions are evil. Because I oppose Trump my actions are good.
Step 3: Trump hates MS-13 and calls the animals, therefore I love MS-13 and call them immigrants.
Step 4: Immigrants = MS-13.
Their circle of logic now complete, the 'Progressives' are now in full agreement with that first Trump's statement, when he called immigrants criminals, rapists and drug dealers.
