Since there's absolutely no evidence that the white chantry circles make a society any safer: no
I can't believe I have to explain the correlation between "keeping bombs away from people" and "people being safer".
If the majority of mages are within a Circle, then incidents will either happen within the Circle or the number of incidents ocurring on the outside will be severely diminished because, again, most mages are in the Circle.
Uldred is a good example. How many non-mage civillians did he kill? Zero. How many would he have killed had he been in Denerim?
If all mages are outside, then all incidents happen outside in which case, more people die.
It's just basic logic. The pro-mage position is to endanger a 100 people so that one mage can have no restrictions.
We only have this quote... "Some are saying, however, that this needs to change. They remind the world that mages are not controlled by templars everywhere in Thedas: not among the Rivaini witches, the Dalish keepers or the Tevinter magisters… and those societies are, arguably, no worse off."
Considering all those societies are ruled by mages, whether it be a tyranny or a benevolent oligarchy, I can only assume the author is a mage supremacist.
And there's Leliana's epilogue, of course.
Which never mentions safety at all.
