a storm in a teakettle

A disproportionate reaction of anger, concern, or displeasure over some minor or trivial matter. (A less common variant of "a tempest in a teacup/teapot.") If you ask me, these protests are nothing but a storm in a teakettle that's been stoked by a media campaign of misinformation. I really think you're making a storm in a teakettle over this. It's just a tiny scratch on the car!
