Thank you for explaining. It isn't hatred that I felt. I was embarrassed by their carelessness, disregard for those who thirst (throwing around empty water bottles and then buying snacks without sharing was pretty rude considering an entire village had fed and sheltered the volunteers). So, yes, overall it did appear they disregarded the locals.
As a white person, and knowing the Mexicans were attributing their behavior to being white, I was apologetic. Not all white people are so dismissive of others.
In terms of Christianity, and this being a Christian missions trio to serve orphans, I held an opinion that we were to act better. By better I mean more graciously. We were in their world, to serve THEM. They were not there to serve us. But they did. And VERY graciously. This was a missions trip sponsored by our church. We were to be a positive reflection of Christian service.
If you want to know more drama, they volunteers snuck marijuana INTO Mexico (putting all of us at risk while crossing the border). They hung black silk bras from trees. The leaders let the teens go skinny dipping even though the leaders of the orphanage were trying to keep the kids from doing the same. It was as if the volunteers had their own rules because they thought they deserved it rather than trying to follow the rules of the orphanage. And they never said thank you for the meals or hospitality.
