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.

Question: Comment: Well. Certainly no red flags there! Here,  take 2 guns and move along.

Answer: Non-obscene


Question: Comment: Goodness knows where you are coming from. 

The Catalan flag and its symbols is hated by the Spanish Government as it unifies, sort of, a historic area and language with much talk of independence / home rule. The old SA flag, if memory serves me, dates from about 1912 not 1948.
The destruction of books, Art, banning, etc was done by many who disagreed with them, whether the Nazi or today's UCT, or students of a destructive sort, educatable, I am less certain. 
I was not educated in SA but UK. 
Paper was not 'discovered' but manufactured, perhaps in Egypt, perhaps in todays Iraq, but out of reeds and not at all todays paper. Why you mention it I don't know.

The rest of what you say, were I to print it, would be consigned to the dustbin!

Answer: Non-obscene


Question: Comment: In 1988, two young American men beat to death Mulugeta Seraw, an Ethiopian graduate student. Mulugeta’s only crime, according to them, was his skin color. 

As it turned out, these men were members of the White Aryan Resistance (WAR), a white supremacist group founded by neo-Nazi and KKK grand dragon, Tom Metzger. 

Metzger began his racist career in 1979 by patrolling the U.S./Mexican border in San Diego as a private citizen stating he was concerned about illegal immigration. 

When he began hosting a television show aimed at white nationalism, his anti-immigrant stance quickly became an anti-anything not white, Christian and male. Additionally, he sponsored a rock concert for Aryan youth which is how the Seraw killers were introduced to his racist gutter spewed antics.

The Southern Poverty Law Center sued Metzger using the vicarious liability concept and won.

Answer:
Non-obscene
