Right now this very moment all white people need to immediately take an active part in their local government and community.What do you propose non white men do?
Whites need to band together as a people and work towards building a new society separate from their governments, religion or whatever else is holding them back.
Whites need to stop relying on corporations and the government to be the tape that holds together their world.
If all Americans and Europeans could band together and create a breakaway civilization all their enemies would starve off and die overnight (well it might take a while).
Oops I read that as "What do you propose white men do"
As for non-whites, I would suggest allying with racially aware/nationalist whites that don't want to kill you.
Become their friends, understand their wants and plans and find out how you can make that work for you.
Form a community with your own ethnicity or those like you and start making plans for how you'll live once the US collapses and the system that has been holding our society together disappears.
