It is fully within a person's rights to be allowed to have and express their thoughts in the form of opinions. It does not have to be your business ... and you do not have to make your goal in life to have an opinion on everyone else's opinions.
Let me just make something clear for those that also seem to have no sense: Blaming others is not strength, playing the victim is not strength, getting angry is not strength, and accountability is FAR from weakness.
