Cringe to fingernails on a chalkboard

It would be like a radio show talk host who asks the audience about controversial topics such as abortion, taxes, gun control, etc. Basically it is bad because the radio host would be asking them biased questions that really did not need to be asked in the first place because there are so many different opinions in the world. 
Hope this helped!
Have a nice day!
