There's fighting and fighting. Don't fight unless God is with you.
Acts 5:39
But if it is from God, you will not be able to stop these men; you will only find yourselves fighting against God.’
2 Corinthians 10:4
The weapons we fight with are not the weapons of the world. On the contrary, they have divine power to demolish strongholds.
1 Timothy 6:12
Fight the good fight of the faith. Take hold of the eternal life to which you were called when you made your good confession in the presence of many witnesses.
James 4:1
Submit yourselves to God
What causes fights and quarrels among you? Don’t they come from your desires that battle within you?
