Now...Opinions can be an insult and still an opinion.
As written in the Cambridge dictionary: An opinion is (one of) the ideas that a person or a group of people have about something or someone, which are based mainly on their feelings and beliefs.
A judgement backed-up by facts.
For instance, mayorbill11 has made my ignore list. In my opinion, he has yet to post a worthwhile note on any topic. His sole purpose seems to be to antagonize and irritate other people into a negative reaction. Look a few posts up on this thread.
This is an opinion, based on his numerous posts that I have read on this forum and others. It is my opinion.
For someone to have an opinion that another person is a waste of air is not wrong. If they have adequate reason why they state it such a way.
So yes, insults hurled at another purpose under the guise of an opinion is wrong, and GTplanet doesn't need that. Opinions discussed and supported with knowledge are always welcome at GTplanet.
