Dutch guy getting beat up after doing blackface: "Waah! It's a important cultural practice! You don't understand, it has nothing to do with race, Dutch people just have folklore stories about dark skinned fantasy creatures coming and stealing our stuff! You're the ones making it about race!"
Black people started using the n word among themselves casually, doesn't mean other people can just copy it and shield themselves from accusations of racism by saying Black people were doing it first.
Now you're just being obtuse. It's really sad you think what you're doing isn't obvious. For the onlookers: This is what happens when you don't get mental and social stimulus.
I'm happy you've got a Chinese friend that tells you it's okay to be racist.
The fact that you're unwilling to acknowledge the fact that this redditor shibboleth got popular amongst a bunch of white people has nothing to do with them finding yet another socially acceptable way to be racist is telling a lot we already knew about you.
If a reactionary org of black people (I dunno of one but I'm sure there's some church or something) had satirically depicted Obama as curious George, do you think you could get away with calling him a monkey without being (rightfully) called a racist?
