More of My Confusion

WHY do people ask for an explanation if they have:

• No intention of letting you speak more than 4.2 words before interrupting you because they already have preformed notions of what the answer will be, usually something that makes you look like a retard, a scam artist, or just a plain old jackass (even if their version of events is way off base).
• The ability to twist those 4.2 words to fit their own malignant schemes to purposely make you look like said retard, scam artist, or just plain old jackass.
• The inclination to misconstrue any information you might have imparted upon them, had they allowed you to speak your piece without interrupting and took what you had to say for face value rather than with the spin they were so courteous as to put on it for you.
  
• The need to act like the explanation, if and when you finally do get it out in its entirety and with any coherency, went in one ear and right out the other without sticking to SOMETHING in the space between?

Second, WHY do these people then tell you that if you have any questions, don't hesitate to ask, when they have no intention in the first place of answering them - after all, they're the ones who have the right to question you, not the other way around.

YOU MIGHT HEAR ME, BUT YOU'RE NOT LISTENING TO WHAT I AM SAYING.
