I make this short and simple:
1) "all polarized glasses are the same" is like "all cars are the same" <== true or false?
2) "Buying a cheap $10-20 polarized glass from Walmart is the same as Costa or Mauii Jim" is like "Buy a Ford is the same as buying a Mercedes or BMW" <== true or false?
Here is the bonus question for all anglers:
"Buying a Shakespear rod is the same as buying a Waterloo / Laguna /GLoomis since it will catch fishes" <== true or false?
