I don't do the "no true Scotsman" fallacy. These people ARE Christians, just jerkwad Christians. Even in the bible, you see followers of Jesus with various attitudes, from laid back to extreme arrogance (so bad that even those who liked you hated you). The Christianity of James is not the Christianity of Peter or Paul. The bible notes that after Jesus, people tended to gravitate toward the apostles who "floated their boat" more.
I don't know that all of them actually understand what is being done or authorize all the practices, but this is the result.
I find that lots of people rarely examine possible outcomes. Now, I admit that I seem scatterbrained sometimes (sometimes? LOL), but it's because I tend to run a lot of mental simulations. For me, it's not good enough to have a Plan B, but also C, D, E, F, and variants of all of the above (God, I'm so lame).
I distrust the "I didn't understand that would happen." I think they tell themselves that to sleep at night. People all over the world CAN'T be that brain dead. If you decry wearing a seat belt or a helmet ... I find it hard to fathom that it's impossible to entertain the possibility injury is on its way. I mean, I can get not wanting to admit we're vulnerable, but ... daaaang. When you have an ideology that promotes exclusion based on characteristics with no verifiable objective harm to be assessed, the logical step is ... well, crap like the Ghana situation.
