The author I think doesn't understand this bit in Romans. It doesn't say to heap burning coals on your enemies head, It says

Do not repay anyone evil for evil. Be careful to do what is right in the eyes of everyone.
18 If it is possible, as far as it depends on you, live at peace with everyone.
19 Do not take revenge, my dear friends, but leave room for God’s wrath, for it is written: “It is mine to avenge; I will repay,”[d] says the Lord.
20 On the contrary:
“If your enemy is hungry, feed him; if he is thirsty, give him something to drink. In doing this, you will heap burning coals on his head.”[e]
21 Do not be overcome by evil, but overcome evil with good.

This is something I have a very hard time with, and if it said "and then heap burning coals upon their head" I wouldn't have anywhere near as hard a time with it. Instead it is saying show kindness to your enemies and it WILL BE AS IF you heaped burning coals upon their head.

Excellent! This whole “love your enemies” thing is so counter to the natural impulse to (what we imagine) win for Jesus.

Folks who actually DID that would probably get ridiculed, scorned and worse.
