I'm not sure I understand your point: if we assume that the fact that
my adapter burned indicates that my particular adapter must have been of
very poor quality, than this implies that such adapters in general are
not dangerous (which, as I've noted, is supported by the fact that
reputable companies sell them, with no warnings that they're dangerous).
