... Your descriptions of the cultural nuances of the area are accurate, but the emphasis on violence and crime are a bit over the top (this isn't Espanola)...
...People that are spending 6 months there skiing typically will not be exposed to the darker side of things (this happens most often when people decide to get involved in the local drug scene, which exists in every city across the nation whether you are aware of it or not).
Sorry, but I'm going to disagree with you on those two points above. Taos isn't Española, and doesn't have as big a heroin problem, but the property and violent crime figures are way above average. And I assume it's about more than just skiing for the the OP - there's a family, and children going to pre-school and unless you isolate yourself up in the ski valley, you're likely to encounter at least some of the unfriendliness I mentioned. You can isolate yourself from that stuff, especially if you have money (Roberts/Rumsfeld), but that doesn't mean it's not there.
And the people I know that have been hurt by the darker side of things there were not involved with the drug scene. And please, I'm aware of 'the local drug scene' in other cities. But Taos' issues are much greater than the drug scene. I don't want to go into stories about new residents homes being burned, or physical threats and worse, or cultural frictions and harassment but those things are real and some have happened to people I know...and they aren't involved in the drug scene.
