No not really, I am way left of Biden, universal Healthcare, free community College, strong social safety net etc. are not radical left ideas, they are centrist.
I also know enough about history to understand that power systems formed around Marxism communism or anarchism are not inherently good or just when put into practice.
I despise the wholesale slaughter of civilians by the military industrial complex, I also despise the violent crushing of dissent by 'communist' or 'socialist' governments.
A good and just society will always be a mix of different 'isms' and marxism definitely needs to be a prominent part of the mix. I'm against total ideological purity, be it capitalist imperialism that can justify industrialized human suffering, or naive tankie bullshit that can justify being on the side of the tanks in Tiananmen square.
