We all have opinions, no matter Yes or No, but here have another status named “no opinion”.
Like a vacant space, we don’t know what it would be used in the future, there is no conclusion at this moment.
But this “no opinion” would become a better viewpoint later, nobody knows its value, maybe unbelievable.
The value of “no opinion” may depends on the process of becoming another opinion.
So, we need to show others, there is an opinion called “no opinion”, it also has a value, big or small.
