When you reference part of society in an obscene slur or put down, the part of society you refer to you are describing as so horrible, so useless so not worth a damn that they are the worst thing you can call someone.
When you call an unfaithful man a dog you are saying he is nothing but a walking erection who like dogs, will mount every female of the species he can! Am I right girls?
The term thug used to describe someone prone to instant violence when upset, goes back centuries to a lethal Indian cult of killers who swore to eradicate the British invaders from their homeland they were called thuggies today it’s shortened to thug.
So you think the person who is n your face book wall is an idiot so you call them a retard? when you do this by the common reason used by society for creating a slur or a putdown you are saying a child who no fault of its own is born with the cord wrapped around its neck stopping oxygen to the brain or a child born with anyone of over a thousand mental illnesses or genetic differences causing diminished capacity are the lowest of society. You are putting them in the same grouping as the dog or the thug or the feeling you have when you scream homo to the gay kid across the playground!
Wow by your rules is epileptic diabetic Down’s syndrome cardiac patient paraplegic or blind a slur? are all we the disabled according to your hierarchy of existence mere fodder for your mealy mouth and uncontrolled hate?
If we are then you my friend just became by societies standard something to be yelled in hate as a slur, because your idea of “if you’re less than perfect you disgust me” has no place in decent society. The difference between you and those you condemn, is we have the ability to get on with a life that is productive and filled with love you I fear may just be sentenced to the bare basics of waking sleeping and breathing.
Unfortunately for you, joy is reserved for those who think and care.
