Why would I be mad? Are you saying that your words could potentially made someone mad? It's not a good translation. Jesus isn't equal to God in Scripture. He said so himself so you need to take it up with Jesus.
Jesus did not consider equality with God something to be grasped. Not the other way around. This is something obtainable for the church of Philippi which is what Paul's subject it. This entire passage is in reference to what the church of Philippi should be thinking about themselves.
Philippians 2
5Let this mind be in you which was also in Christ Jesus:
6Who, existing in the form of God,
did not consider equality with God
something to be grasped,
7but emptied Himself,
taking the form of a servant,
being made in human likeness.
8And being found in appearance as a man,
He humbled Himself
and became obedient to death—
even death on a cross.
