Shouting something like "stop" or "enough" or "go" at toddler wont cause him trauma. What will cause trauma to your kid is yelling at him something like "you stupid f**, good for nothing looser, I hate you ..."

There is literally zero dichotomy between preventing toddlers doing crazy stupid & dangerous things vs causing them trauma via words. Toddlers can be annoying and don't respect you are tired mentally or emotionally. People loose their emotional control, it happens, especially when there are other stresses. But, saying that it is about safety is simply not true.
