TASK DEFINITION: In this task, you are given a public comment from online platforms. You are expected to classify the comment into two classes: insult and non-insult. Insult is any lanugage or act that is disrespectful or scornfully abusive.
PROBLEM: Comment: Maria Goretti. Now, lugubriously, patron saint of rape victims.

SOLUTION: Non-insult

PROBLEM: Comment: Probably, like you, an idiot.

SOLUTION: Insult

PROBLEM: Comment: Heh. Silly liberals. "Alt-left: Firm believers in a Liberal/Social Democracy ex.( Liberties mentioned in The Bill of Rights etc...) but with a type of Socialist Market Economy; 
An alternative political movement that seeks to unite those who feel underrepresented or marginalized by current mainstream political channels, who seek to adhere to left-wing policies while rejecting what they deem the regressive left agenda; "Identity Politics", "Censorship in College campuses","Trigger Warnings", "All whites are racist", "All men are sexist" and other bullshit narratives."
"Nazis" by name are socialists and therefore are on the left. ("Nazi" is the contraction of "National Socialist.") The KKK was an invention of southern democrats in the 1860s. The rest of your post is regurgitation of freshman college snowflake drivel. Please learn to think on your own.... it's a hard world when you're no longer surrounded by like-minded airheads that think talking points are intelligent thought.

SOLUTION:
Insult
