I do have black friends. They are smart and do well for themselves. They are proof that there isn’t any remaining systemic racism. We had a black president for goodness sake. Their families embrace the white European culture instead of the white cracker culture. They were raised to value an education and apply themselves. That doesn’t always happen.
If I were to create a city that can withstand the downfall of society, I would want to put a defensive military fortress at its center. Right now, they don’t run it, but when the shit hits the fan, they can inherit an arsenal of protection.
