The greater good
Meaningless euphemisms. Whose greater good? Defined by whom? Using what criteria?
This is my own opinion here, but societies do not have rights. Governments do not have rights. Cultures do not have rights. Religions do not have rights. Corporations do not have rights. Families do not have rights.
These are all abstractions. The only beings that have rights are individuals. It is the will and committment of individuals that give these things any weight.
Why? Because a bunch of Enlightenment era folks recovered some Greek humanist thought and decided that was the way to go.
Presumptions of right and wrong
And those presumptions have always reflected the times folks lived in.
