It's just hard to believe that a pastor would allow his daughter to work there. The ones I know; no way. But of course they believe in Yahweh not Allah or Money and aren't into prosperity preaching...
His daughter is 18 first of all. What the people filming this are saying to the preacher is more or less “okay you can’t control the actions of your adult daughter but you don’t have to contribute to it by driving her here.” In other words let her find her own ride to the killing center.
I agree with them. Let her find her own way there. If she can’t get a ride, oh well.
