Right or wrong?

I understand that some things can be correct or incorrect, like spelling or answers on a test, but what I don't understand is why some people think that our reactions, thoughts or feelings are correct or incorrect.
The way I see it is that they are shades of grey, "a hairy subject" that is neither correct or incorrect. It simply is what it is, which I see as favorable or unfavorable rather than right or wrong.
This 'note' is a result of people consistently telling me that I'm right or that my opinion is wrong. I don't like to think that my thoughts, feelings or actions are correct or incorrect, it's an opinion of which we are all entitled. I view opinions as a beautiful and unique thing. We all have our own point(s) of view. It's like we are all looking through a camera lens at the same object, and once we express our perspective on the subject we can compile the information and create a dimensional understanding and be more capable of grokking [1] the situation at hand.
I've decided to throw out right and wrong from my vocabulary, primarily because I've noticed within myself that it naturally evokes a defensive reaction and also because I'd like to respectfully embrace others points of view in their thoughts, feelings and/ or reactions.
Correct or incorrect I will use for the school books, but I will not ignore the emotional and spiritual shades of grey.
