Missionary work is one of the main tools used by colonial powers. Sure, you go and get your experiences with native people, and you come back with memories and pictures and all the feel good you brought from your encounter with loving and grateful people. You never get to see the destruction and degradation you left behind, nor the way the colonizers and oppressors will use the tools you left there for them. You can remain blind to the way in which you came to a foreign land to tell them their native ways are wrong, that they need the Bible and you church, that their millenary spiritual ways are wrong. You come with money and charm, and drop a paradigm on them designed to make them abandon their wisdom and ways in favor of your Jesus and your cult. How different it would be if you came here with the simple desire to learn and be a guest, with respect. How different if you didn’t have the putrid desire to change the natives into followers of your ways.
