That's a stupid question

I've been watching too much news lately. Maybe this pet peeve blog is the result of too much cabin fever - but here goes.   

I'm tired of guests being interviewed answering a reporter's question with:  "That's a real good question"; or "That's an important question"; "Thanks for asking that question; or various derivatives.  

Let me first say that we were taught in school, There is no dumb question or always ask when you don't understand.  So when a person say's that's a real good question, would they be telling the truth if your question was not a good question?  Or if they don't respond measuring the quality of your question, are they by default considering your question dumb?

Maybe they are just "buying time" to think about their response.  Maybe they are just over aggrandizing you with platitudes.  Maybe it's just an irritating habit similar to saying ugh, and ah during speaking to fill silence. Maybe it is just a walkie, talkie version of acknowledging hearing - "Over".

Colin Powell said "There are no such thing as a stupid question, only stupid answers"

I would add - a likely stupid answer begins with -  "I'm so glad you asked that question, it is so..... important".
