When your aim in traveling is to be a better citizen of the world, you have to be open to learning about the world. Traveling, to me, is not about stimulating the senses, although I love this too, especially when it comes to food. Traveling takes you out of your comfort zone, and this makes you open to learning.
You may say, past is past. This was another time. Too bad this happened, but so what does have to do with us today? My answer is, there is injustice today! Maria mentions in the documentary that she uses Jesus as the model for what she does. "If Jesus Christ can die for injustice, then so can I." I don't think I have that kind of courage. I think God knows that because in my life, I am not called to put my life on the line for a great cause. We do live in a comfort zone, especially in Hawaii, but travel takes you out of your comfort zone. Travel and connecting with other people's stories have the potential to make us more empathetic, more of our brother's and sister's keepers. I don't want to be "just" a sensory tourist, interested in the sights, tastes, smells, sound, and touch of a different place. That is part of traveling and I love it. But if it doesn't somehow make you more educated, more knowledgeable about the world, its culture and history, then it is selfish.
Today, in Mexico (far from where I'll be) there is terrible news about student teachers who had been on their way to stage a protest against the state government. 43 of them have "disappeared," last seen being taken away by local police. Yes, it happens today, and it is happening in a country that I will be visiting. No, I am not afraid. Also today, in the US, unarmed US citizens can be shot and killed if they are not the right color. So, yes, there is injustice and cause to fear everywhere. And it is not Ebola.
