Do you view the United States as an imperialist power? Either currently or in it's past? If in it's past at what point do you believe it stopped behaving as an imperialist nation.
This is foundational level of understanding the world we live in and it's history, how that history got us to the present political climate. And if you're reaction to someone trying to have a conversation about it is to lash out like you have, then I have to ask another question.
Who is the idiot here?
Rail workers do not have the proper time to fully inspect cars and arrange them in the proper order due to understaffing and the high volume created by maximized rail schedules that prioritize profits over safety.
That's a huge reason why rail workers wanted to go on strike before there was bipartisan cooperation led by Biden to take away their labor rights.
