For me, I am in the camp you are in. I am open to what others have to say and I learn from that and refine my thoughts and feelings on it. I enjoy a good debate for the sake of it, but in the context of your question it is just a matter of disagreement. Hell, I have no problem admitting I am wrong too. The people I have seen take the dislike point of view seem to take the disagreement personally even if it was not meant to be personal. Others simply take it as conflict, and don’t handle conflict well. And then there are some people that are not open to the thought that there could be anything different that their beliefs. In my line of work, I can have an initial belief and plan, but need to flesh out the best approach with discussion that can get very political and heated.
