Final answer:
A person adhering to principles of social justice and equal rights is at the 'post-conventional morality, Stage 2' level in Kohlberg's theory of moral development, where morality is based on universal ethical principles.
Step-by-step explanation:
A person who commits to universal principles such as social justice, equal rights, and respect for the dignity of all people is demonstrating moral principles that align with Lawrence Kohlberg's highest level of moral development: post-conventional morality, specifically Stage 2. Kohlberg's theory postulates that during this stage, individuals make decisions based on universal ethical principles and the belief in the equal worth of all beings. They understand that laws and rules are not infallible and that moral reasoning stands above the law in certain situations, much like the Egyptians in 2011 who protested against a legal but morally questionable government.
