Everyone has an opinion. People have opinions about opinions. They think their opinion is more valid than those of others.
We all believe that no one can feel the same way as us, for our experiences and world view is different, maybe we have undergone more turmoils which has made us wiser.
But at the end of the day, all opinions are equally valid and equally invalid.
It is an interpretation of facts. Your interpretation and understanding of the same data will be different than that of someone else, but that does not mean that you should despise someone else’s interpretation.

Different viewpoints, different opinions is what makes the human experience grand. Let us have a mature understanding and be tolerant of other’s opinions.
Well, that’s just my opinion!
