Ostriches are very noble people...
Richard:
Ostriches hide their heads when they are scared: it is their natural response. I suppose that, considering the times we are living in, hiding our heads might be the best strategy. You asked, is it possible to filter out all this free floating hostility? Well, it depends on how much practice you have at doing this and how tired you are. In my case I find that, when I am not too tired, these things don't bother me that much. When I am overworked, overflown, over-stressed, it becomes a bit more difficult.
However, one thing certainly seems to work, at least in my case. I always remind myself that this situation has been going on in the industry for the last 10 years and that it does not matter where I live, which company I work for and which culture I have to deal with, it will hardly get better. We are dealing here with a new paradigm: "The Migratory Pilot", which has become more generalized with the advent of globalization, and it might take years for things to settle to a point were they become comfortable again. Until this happens, we have to learn to cope.
Going back to your ostrich analogy, ostriches are also very good at running. So I guess that, when the hole is getting to small for your head and you need a bit of fresh air, running in search of a new hole to hide your head is also an alternative. Therefore, when things get too stale where you are "Run, Run, Forrest, Run!!!"
