The notion that "all cultures are equally valid morally" is a dangerous intellectual retreat, a surrender to relativism that ignores the undeniable existence of universal ethical principles. To claim moral equivalency between cultures that champion human rights and those that systematically violate them is not only absurd but intellectually dishonest. Are we to pretend that honor killings or female genital mutilation are merely "different" moral perspectives, equally valid as the principles of equality and bodily autonomy? Such a stance actively undermines the very idea of progress and justice.
