Jonbouy, to answer your questions:
1) I am not an arbitrator, just expressing my opinion.
2) I would say that you are engaging with me and my comments, and justification is not based on whether you agree with them.
IMO, you certainly do have the right to express yourself as you are doing. I also agree with you that botlling things up is generally not healthy (as I am one who can be guilty of doing just that).
Where we will likely have to agree to disagree is that when disputes arise, I think that honey works better than vinegar. Using harsh words can incite the other person to respond with equal or greater harshness, and the conflict often ends up escalating instead of being resolved.
