Collum Lune

Prompt from Amy Kay Poetry on Instagram (not me!!) is to write a collum lune poem which is a simple form poem of 3 lines, first line three words, second line is five words, and the third line is three words. She then gave helpful instructions to go get a book, turn to page 22 and use the 3rd or 4th word in my poem. The word I found was "barbarian".  I was thinking about who seems foreign to me as if they are from a different world and I happen to peruse the internet and see some acquaintances of mine express doubt about climate change. That person may as well be speaking "barbar".  I don't understand them.
