Yeah, but that actually comes back around to the "need to know more" part. LW obviously knows very little about religion in Uganda *or* mission trips, but still feels a moral obligation to judge. Most "mission trips" from most US churches these days are more like voluntourism than proselytization. If this was a real conversation, the person was probably going to a community with an established sister church and doing something like construction or landscaping work.

There's still a whole grab bag of moral and ethical issues with that, don't get me wrong, but LW is probably very wrong about what's actually going on.
