What do you think about me trying to prove my point to my friend?
What point do you want to prove?
We are having a debate about religion.
People prove their points to win an argument. If you feel you are right then yes, you should prove that point.
Well then I'm going to prove my point so hard that he will have no choice but to accept it!
You are entitled to believe in what you want to and prove your point. Just understand that although you may express your beliefs, it does not mean that others will agree to them.
