Driving while measureably impaired by alcohol is certainly in most cases more risky than driving while not impaired by alcohol.
But most people would likely be shocked at how relatively rare it is for a legally drunk (0.08 bac or higher) driver to cause harm to themselves or to others.
Me? I play the preferred odds and don't operate a motor vehicle if I'm measureably impaired. But I don't burn much energy ragging on people who might do otherwise. If they've made the dubious choice to behave like that, they'll get whatever consequences follow. Which, as I first stated, is usually nothing at all because nothing of note happens between the time they get behind the wheel and the time they get out of the car at their destination.
