TASK DEFINITION: In this task, you are given a public comment from online platforms. You are expected to classify the comment into two classes: obscene and non-obscene. A comment is obscene if it is considered offensive to the public sense of decency, for example because it too obviously relates to sex or contains language regarded as taboo in polite usage.
PROBLEM: Comment: In other words, you had no idea that, proportional to population, cops shoot white folks about half as often as they shoot black folks.

So you can't play this game. You don't have the ante.

SOLUTION: Non-obscene

PROBLEM: Comment: American crap, what an ugly comment.

SOLUTION: Obscene

PROBLEM: Comment: "Or the Stalin statue in Virginia!"

Yeah, that is very wacky.  At first, I didn't believe you but here's the reference I found from The Daily Signal, June 4, 2010:

"This Sunday, people around the world will honor the 66th anniversary of D-Day, when over 160,000 troops from the United States, Britain, France and Canada bravely stormed the beaches of Normandy, marking a turning point in World War II. In Bedford, Virginia, a memorial to the invasion will be unveiled with statues of western Allied leaders, including President Franklin D. Roosevelt, Prime Minister Winston Churchill and President Harry Truman. The memorial will also include a bust of dictator Joseph Stalin."

It certainly is puzzling why one of the greatest monsters of the 20th century would be so honored. Stalin killed more people than Hitler and many don't even know that.

SOLUTION:
Non-obscene
