I think Flogga's point is that he managed to bond 2000 locations and was not protected. Yet due to the blindness of certain mortals, they accused (and still do) him of being protected all the time.
Furthermore, I agree with a lot of your post. Thakria does not tolerate Mercinaens or those of any other city. They have no freedom and are entitled to none, unless they somehow earn it.
Thakrians as individuals are free to like, admire, defend whomever they wish. As a city though, Thakria will not afford its enemies any sort of freedom. The freedom of choice is the gift of Thakria to its citizens.
