English Language

The internet has been a wonderful tool to help promote education, information, entertainment and much, much more.

One of the negatives of the internet is how watered down the English language has become. Below are some examples:

Example 1: Genuine Faux Pearls
Really? Can someone explain how you something is "geniune faux"? A quick google search for "Faux definition" turned up the following:

Faux - Adjective:

• 1. Artificial or imitation: "faux pearls".
  
• 2. Not genuine; fake or false: "her faux New York accent"
  

Example 2: Dumbledore's wand - "authentic recreation"

• Someone please explain the phrase "authentic recreation". The phrase alone is an oxymoron.
  
• How can you have "authentic" items that never really existed? But let's say that we let this slide, because Santa Claus exists and he eats the milk n cookies you leave for him. Let's assume that Harry Potter is "real" Yahoo explains the possibility of how this could be true
  
  • "This replica of Dumbledore's wand is an authentic recreation of the old wizard's wand" - so again, if it's authentic then why is it a replica / recreation?
    
  • "Made of resin" - Ok, so this "authentic replica" is made of resin? Can you at least make me an authentic recreation made of genuine faux elder wood & a natural synthetic tail hair of a real fantasy Thestral?
    

So my question to you is:
Which is worse? The person who describes the items they are selling as "authentic replicas" / "genuine faux"? or the person who buys these items because they are "authentic"?
