High ethical standards initially seem to be a good thing. Even if we cannot always live up to them, there is value in recognizing and enshrining an ideal. At the same time, ethical standards are not used solely as an object for aspiration. They are also used as a basis for judgment. And that leaves room for high ideals to be weaponized.
The way this works is analogous to racial profiling. For instance, it is well known that in the United States, virtually every driver exceeds the speed limit. Indeed, following the speed limit can often create a dangerous situation. Nevertheless, the police still enforce this ultimately unenforceable law, and when they do so, they tend to pick out members of groups who already receive disproportionate police attention, namely people of color. In the same way, when we’re dealing with an impossible ethical ideal, those who are judged or punished for not following it will often be selected from disadvantaged groups — a phenomenon we can call “ethical profiling.”
This happens most of all when the high ideal is extremely abstract. For instance, we are told that it is ethically most salutary to be non-violent. Though violence may be sadly necessary under certain circumstances, we should aspire to avoid it to the extent possible. In the world as we know it, however, avoiding it completely is often utterly impossible — particularly when “violence” can be so broadly defined as to include property damage, or impeding the normal run of things, or speaking too harshly. Everyone is violating the ideal in some way or other, but only the protestors (by definition a less powerful group than the powers that be) are judged for doing so. This effect is of course amplified when the protestors are black.
We might also think of the demand to cherish every “life” to the fullest possible extent. Really following this demand would require changing literally everything we do every day, even if we’re only limiting ourselves to human lives. Once again, it is an impossible demand, and once again, only the most vulnerable — women with unexpected or unwanted pregnancies — are expected to follow through on it. The ethic of life is weaponized in the service of ensuring women’s subordination and punishing their sexual expression.
None of this is to say that there aren’t people who don’t sincerely hold the ideals in question. For a select few, aspiring to a high ethical ideal becomes a true vocation to which they dedicate their whole selves. The problem arises when the unique achievements of these ethical heroes become a weapon of the powerful — for instance, when the legacy of Martin Luther King, Jr., is weaponized to shame and denigrate the contemporary black community, or when the heroic voluntary self-sacrifice of Christ is imposed as a baseline expectation on women and the poor. In such cases, we’re dealing less with mere hypocrisy than with something like blasphemy.
