I think you started down the right road, but then veered off. I think even for those of us who are not in the majority, there is no line. There is only a slippery slope. We are waiting to see our line. At what point will it be enough for ME to stand in the street and say no more. And that line will not be reached either, because it is not reached; it must be created and recreated at every turn!
The line is never reached, the slope is slippery for all. And that is why resistance must be mandated as part of the everyday for those who wish to see themselves as humane, rational, unwilling to abide by authoritarianism.
