Feel free to call it "The left-wing PC narrative", but that is how racism is seen in 2018.
And it is the same as the convenience store in Harlem. You are judging something with a predisposition based on life experience or statistics. If that means you assume a certain group of people do something without knowing it was them, that's racist in today's definition.
You are free to hold by your own definitions but at least you concede according to many what you did is racism.
Again, pre-supposing a certain race would commit a robbery is racism. Using the power of deduction is not. I do not concede at all that it is racism.
In fact, what you just did is exactly what people of this generation would do. If I can "identify" whatever I wish to be, then what you say to the contrary is racist, bigoted, hurtful, etc. Because you say its racism doesn't make it so. Facts do not care about your feelings. If one gathers in a group on a plane to pray, he is Jewish. It is a fact. Prove me wrong.
There are two reasons I can think of why Lucky didnt mention their religion. 1. He was afraid of people like you that would say he is racist, or 2. That he was embarrassed because of his "Jewishness".
