Also there can no more be a secular evangelist than there can be a dry ocean. I’m stepping completely out of trust in politics here. Being radical requires that.
I believe there are decent people who are not devout Christians. They have fallen out at some point, but still know there is a right and wrong. When they push for right, they are evangelizing to an extent. And they are advocating for God’s will to be done, even if not from within the religious framework. I believe a God still works through some of these people.
