Opinions are something that everyone has, some have the same, some don't.  Why can no one seem to respect other's opinions without being judgmental or having to argue with them and tell them they are wrong?  Opinions are not right nor wrong, they are how a person thinks or feels on a subject.

If you don't like the opinion, fine. State your case, but don't be argumentative or judgy.   Let it go.  If the opinions expressed are always different from yours, then maybe you shouldn't be talking to that person, unless you like to argue and aggravate everyone around you. You know who you are.  People seem to have a need to believe that everyone should think just like them.  Never going to happen.  We are too diverse to think alike and if we all did think alike, we'd be so freaking bored with each other we die out just from boredom.  Being like everyone else just makes you a sheep.  Don't let others tell you how to think.  Think for your self and be your own leader.
