Opposite is derived form the word 'oppose'
It doesn't REALLY mean ZERO or NOTHING....
... rather physically or figuratively the force that would push you back the way you came.
Mathamatically the opposite of 1 is minus 1, not zero.
"For every action there is an equal & opposite reaction"
Means a COUNTER force, NOT a force of zero.
Now this gets a little more complicated when applied multifacited things like feelings or politics, but in general if you eveluate a single characteristic of a thing - it's opposite is a characteristic in something else that resists or reverses the original phenomina.
So Fire is the opposite of Ice - at least in the sense of providing warmth.
Now everyone would understand if you said the opposite of Rich is Broke, or the opposite of Noise is Silence.
But TECHNECALLY the opposite of great Wealth is great Debt & the opposite of Noise (unpleasent sound) is Music (pleasent sound)
Make sense? .
Your Political Opposition are those who fight AGAINST your goals, not those who have no opinion.
The opposite of winning is losing NOT avoiding the challange alttogether.
