To win a race war, all white people need to do is stop feeding, housing and giving money to the non whites. No violence necessary.
It's a good start, but before they settle for a hungry death, they tend to go for animals first. We kinda saw that happen recently. I don't want these niggers to be slaughtering and eating every single elephant they can get their hands on. So it can't be a totally passive method.
Most non whites live in cities. Sure, they'll try to eat what they can find. It won't be much.
