That was a lot of unnecessary emotion and hyperbole for what is effectively a paperwork issue on an international flight. The individual has a different legal name in two different legal jurisdictions. While "American Airlines" is a worldwide company, each local employee is acting in their own self interests so they do not violate the law in that country. But to their credit, the first employee they dealt with did try to flag it as a problem and tried to escalate it, but it sounds like OP just wanted to move ahead without the resolution. From time to time stuff like this happens. If it has this profound of an emotional impact on you, I highly recommend the services of a travel agent. They are getting paid by you to understand what will and wont work at every step of the journey.
