somebody never leaving the place where they were born is not evidence for or against self-determination.

No you're right, it's not sad a person doesn't get to travel. I myself have never left New England, but I've been all over it. What's sad is they don't know other cultures or way of life, then become fearful of them, then hateful, and dismissive.

It's a pathway to ignorance of you aren't a learning seeking person. Those people in rhe class didn't know our state had public transport, and actively thought it was fake, the video no longer resonated with them, as it didn't represent them. That's whats sad.

If you have access and the ability to do something and choose not to, that's self-determination. If you don't have the choice then it isn't.
