Some battles offer no chance of victory

There is no victory in battling with fools.

Those people who clearly prove themselves as either imbeciles or antagonists in your life, Christian, do not let them steal your joy. Forgive them. Do your best to help them if possible,  but if they engage you for battle,  lift your sheld of faith and not your sword to meet their advances,  and they will do you know harm. 

A whip for the horse, A bridle for the donkey, And a rod for the fool’s back. Do not answer a fool according to his folly, Lest you also be like him. Answer a fool according to his folly, Lest he be wise in his own eyes. He who sends a message by the hand of a fool Cuts off his  own feet and drinks violence. Like the legs of the lame that hang limp Is a proverb in the mouth of fools. Like one who binds a stone in a sling Is he who gives honor to a fool. Like a thorn that goes into the hand of a drunkard Is a proverb in the mouth of fools. The great God who formed everything Gives the fool his hire and the transgressor his wages. As a dog returns to his own vomit, So a fool repeats his folly. Do you see a man wise in his own eyes? There  is more hope for a fool than for him.

Proverbs 26:3‭-‬12 NKJV
