When people denounced [former Iranian president Mahmoud] Ahmadinejad for rejecting and criminalizing homosexuality, it should be remembered that was true of the United States until very recently. Women's rights were unheard of. Civil rights proponents were horribly treated, not just in the South. It was awful there, but pretty bad here. Environmental issues did not exist. Opposition to aggression was virtually zero. In fact, so little, that to this day, even scholarship mentions the Vietnam War as beginning in 1965.
John Stuart Mill
This is what writers mean when they say that the notion of cause involves the idea of necessity. If there be any meaning which confessedly belongs to the term necessity, it is unconditionalness. That which is necessary, that which must be, means that which will be, whatever supposition we may make in regard to all other things.
