Racism is a tool wielded by the owner class to divide workers as they wage class warfare against them.
The grassroots development of class consciousness and a united working class is our only way out of this.
if you were in Russia in the late XIX century then yes
but history learns (this is also why we cannot ever have another revolutionary hero, nor another french revolution) so no.
class consciousness and a united "working class" will not help us anymore. a lot has changed since those ideas made sense
