Really, parsing out a post and then demanding that the poster defend it and then parsing out the reply and doing it again seems dramatically rude to me. Now I remember why I stopped looking at this forum last January.
If a mayor of a US city turned over 43 students to a drug gang in the sure and certain knowledge that they'd be killed I truly believe that this country would erupt in rage. It appears that Mexico has, actually... and who can blame them?
We spent most of the 1980s cruising the Sea of Cortez and touring Baja and the west coast of MX down as far as Mazatlan. I suspect that even though much has changed the basic friendliness of the people remains the same. We bought our motor home with an eye towards returning to Baja and revisiting many of the places we loved. But since we are 3 years from doing that we have time to regroup.
Flying to a Mexican resort area - where there are a lot of Gringos and English is commonly spoken - gives visitors a greater sense of security than driving across the desert for a thousand miles. Not to mention the checkpoints with armed men in and out of uniform. And, yes, I consider those tourist areas to be "Mexico Light"; that is, after all, what many cash-paying visitors want.
The SW deserts of the USA offer a lot of interesting places and spending the rest of our lives just visiting those wouldn't exactly be a penalty. So if it costs just as much to go into MX plus having to put up with the paperwork, the corruption, the bad roads, the potential for danger and crappy RV parks we're probably going to pass.
Sure, there are crappy RV parks in the US, and it can be expensive, and there is corruption and potential for danger here, too but since it's our native culture (and language) we can mitigate a lot of it because we understand how it works. For many RVers who do not understand how it works in Mexico that can be a big issue. So it's the total package is that would deter us. The cumulative annoyance of all of that would do it.
And perception, just as often as not, becomes the reality.
