I get what you're saying here, but it is in my opinion one of the most racist countries.
That doesn't mean only white people are racists. Black, Mexicans, Asians, etc.
I agree. U.S. is one of the most racist countries in the world. And yes, whites aren't the only ones who are racist and/or calls racist names to others - for example, some people call Mexicans "wetbacks," but that's not really a racist thing, it's more of a name call. An insult. Spic, to a latin or hispanic origin, is racist.
Everyone is a bit racist, I don't care who you are. You're just lying to yourself if you don't believe that.
There are times that you don't realize you're being racist, but this story right here? This teenager doesn't have any remorse for calling some black lady, a Nope. He/she deliberately called her the n word without any thought as to what the word means to black/brown folks. It's a touchy slang, not one of those easy name calling thing you can just say to a black/brown folk.
And, yes, I also agree that this whole racism thing is getting worse. It's not getting better nowdays. Some people are just ignorant or just flat out stupid. People need to realize that being racist is not a good thing.
