Talking about opinions, I have mine, you have yours.
Opinions are not facts. They remain as opinions unless proven otherwise.
So, your opinion or mine does not always has to be right.
We should learn to agree to disagree.
Unless it affects you and whatever that concerns you, just be calm and move on.
If it's really important, fight for it.
If it's not, let it go.
Shame on you if you think everyone else is dumber because they are different from you.
What's your opinion about me?
