Why is penning racism on white folks on an almost exclusive level fun for you, black folks? (See what I did there).

Your finalizing question may not intend to and perhaps I'm thinking you're just referring to the white folks that are indeed racist, but it comes off rather badly. But in reference to way it is structured, you might as well be inquiring:

Why is anti-Semitism fun for you, black folks and/or Muslims?

Why is anti-Catholicism fun for you, Protestants?

Why is anti-LGBTQ fun for you, straight people?

It is when things involving racism are worded like this, it makes a person like me embittered and indifferent, because it appears that you're speaking out against racism, yet this phrase you is itself racist.

Or prejudice, if you wish to use that term over "racism".

Oh black people, Muslims, straight people and Protestants, can you honestly answer these questions

(AND FOR THOSE UNABLE TO DISTINGUISH BETWEEN SARCASM AND SINCERITY, THIS IS A RHETORICAL QUESTION).

It is when people approach racism with this type of question that I no longer take the issue very seriously.
