When I first came here, I arrived with my parents.  It made me a little angry when I would go places with my father and be entirely ignored or worse used for the benefit of my father.  He relied on my Spanish a lot so I was especially annoyed with other men, such as the owner of our hotel would brush off what I was trying to say to listen to my father.  
Now, without my father, I am actually listened to.  However, I think that I would have more patience for that kind of ageism and sexism, because I now recognize it as more of a difference of respect.
I'm not entirely sure what changed my attitude about this, but I'll guess that it's probably seeing male comrade in a different culture light, as well as seeing what respect for elders really means and the kind of respect children have for their parents; patient respect.
I am no longer as staunchly feminist and I think that I'll be able to taking the overriding of my opinion that occurs in the United States much more in stride.
