Not really.
Vivienne clearly sees magic is dangerous "as fire is dangerous" Thus she wants to make sure that everyone free to practice magic is responsible enough to use it without burning themselves or others.
People should be wary of magic. But she also wants those who can safely handle magic to be respected.
I mean, to use her analogy, fire is dangerous. It can damage or destroy property. It can cause painful, even disfiguring burns. It can kill. But it can also cook food, provide warmth, forge metal, sterilize medical equipment. It can bring comfort to others and even save lives. But to do so it must be used the proper way, and not run wild. A properly banked forge can be a boon to a village. A fire at the smithy can burn that village down.
