Logic 101? I thought we were talking about religion. What do the two of them have in common?
Who said the high murder rate countries are Christians? Wikipedia!!
en.wikipedia.org
Down to 38, first non-Christian country. Iraq, a country the US invaded and put a puppet government to run. 45 is the next one, Ethiopia, Yemen at 54.
We can even see South Sudan and Sudan, both were the same country until a few years ago when the Christian south gained independence, their murder rate is 14.9 while Muslim north Sudan is at 5.1, lower than the US....
We don't need to "define terms", we know which countries are Christian. Even if the people aren't Christian, Christianity has shaped those countries and made the people who they are.
