American Socialist Democratic Party: A current form of New Facism wherein large corporations with global interest and corrupted politicians subvert the people for their own benefit and rob the treasury.
Corporation oppression of the peoples' rights, for example you must wear a face mask/get vaccinated, before you can buy anything at Walmart.
