Trump has few if any discernible political positions. His revolving door group of advisors nearly all do; a Trump position is usually the transmission of the last words whispered in his ear by the current crop. Trump has one political goal, to get re-elected, and one policy priority, to dismantle and destroy everything that Obama built during his terms. These policy goals usually mesh nicely with the wishes of his "base", but if you notice lately he will abandon them in a heartbeat if he feels that they are threatening his first directive. For example, conservatives want to end the $600 weekly unemployment bonus, Trump realizes that extending it will help the economy and thus the only real argument he has for another term, and further, that if he can unilaterally extend it by executive action he will get the credit among the hurting working class.

Black Lives Matter in a national phenomenon, the organization over which you are obsessing is as near to irrelevant to this phenomena as an organization can be. The vast majority of movement supporters neither know or care what the fearful "founders" desire or plan. Should they find out about the "Marxist" goals and beliefs of these activists they will simply drop them like a flaming bag of dog shit, and continue on with the goal of changing the systemic racism that plagues our country.

The point of unwanted weather or capitalism is that either one is pretty much inevitable. Like the mice choosing one to bell the cat, people’s railing against capitalism is a pitiful exercise in futility. They may have dozens of gripes about “the system”, they have no concept of the power and inertia of the system. Fearing the words or actions of the very few “Marxists” out there is like irrational. They are irrelevant to the flow of events and doomed to see their hopes dashed. They do however seem to serve as useful straw men for one side of our political divide.
