This nut, Living-toad, was upset about white people eating in a black-owned restaurant. For one thing, he's white himself and frequents the restaurant.
For another thing, if the white people who were eating in the restaurant had said they didn't want to eat in a black-owned restaurant, this deranged troll would probably call them racists for that.
The final word is that the guy is a lunatic. But there's plenty more like him infesting the classrooms of high schools and colleges across the country.
Liberalism/leftism is a form of insanity.
