The PC Debate: "Left" Behind or the "Right" Word

The political kerfuffle may be decided with words. Which do you prefer?:

• A lie or a factually false statement
• Bum or motivationally challenged
• Crazy or serotonin deficient  
• Example: 
• The sex-crazed bum left me and my kids broke and homeless. 
• The motivationally challenged libidinous serotonin deficient sperm donor abandoned the children rendering us a single mom family without a domicile or financial sustenance.
• Criminal or behaviorally challenged
• Example: 
• Lockup those ghetto-bred criminals. 
• The behaviorally challenged citizens who live in an economically disadvantaged area have an environmental induced tendency to behave in an improper manner that incarceration exacerbates.
• Temper tantrums or bipolar tendencies
• Garbage or sanitation challenged products so that a garbage man becomes a sanitation engineer
• Custodian or hygienic artist 
• Failure or deferred success
• He failed because he couldn't read, write or do arithmetic.
• His deferred success was no longer delayed when academic qualifications became equalized for all students so that no child was left behind.
• Fat people or the hormone induced rotund
• Foreign food or ethnic cuisine
• Example: 
• Fat people get high blood sugar 'cause they don't eat good"
• Ethnic cuisine of the Mediterranean variety may help the hormone induced rotund to attain a svelte physique that enhances a healthy life-style. 
• Housewife or domestic engineer, or, perhaps, CEO of a small cooperation 
• Natural disaster or climate change event
• Hot weather or increased global warming confirmation 
• Politician or self-serving autocrat

In summary let us endeavor to articulate in a culturally diverse manner so that our inoffensive communication enhances harmony with all people can be expostulated with less verbosity. In plain speech: Speak kindly and clearly.
