It's not the mole hill they are worried about. It's the volcano they can turn it into.
It's just how it works. If the last eight years taught us anything it's that this is the normal volume of politics right now. One side screeches and the other responds. It's annoying, but it's what we get to deal with for the time being.
The only way to really deal with it is to remain calm and not freak out at the people freaking out. It's the only real defense IMHO.
