What libertarians assert is simply that differences among normal adults do not imply different fundamental rights.
Libertarians argue that no normal adult has the right to impose choices on other normal adults, except in abnormal circumstances, such as when one person finds another unconscious and administers medical assistance or calls an ambulance.
Libertarians typically argue that particular obligations, at least under normal circumstances, must be created by consent; they cannot be unilaterally imposed by others.
Group personification obscures, rather than illuminates, important political questions.
