No, blaming lawyers for filing idiotic lawsuits is like blaming the linebacker for sacking the guy selling the wrong brand of beer.
Lawyers generally don't file lawsuits they don't believe can win them money. Even "nusiance" lawsuits usually risk quick summary judgment if they lack a basis. There are obvious exceptions, just like doctors, engineers, etc., except usually the worst lawyers and abusive lawsuits garner far more media attention as it plays to everyone hating lawyers.
Everyone, that is, until they need one.
