You are a product of your environment, and if your environment is insane, you will be too.

There's only so much a singular self can handle from an environment that is chaotic. Insane is generally not a nice word. Social environment in relation to individual.
If your only point of contact is people who speak spanish, you will never learn english. If your only point of contact is people that think that the world is flat, then most likely you will grow up believing the same. If everyone around you is insane, then it is exceedingly like you will be too.
Again, my belief is that you are a product of 1. Your environment and 2. Your genetic programming. And humans are social creatures, if the people that surround you are all in a certain way, you will probably tend that way too.
I don't know man, I'm not exactly for the idea that insanity is a "social construct", but after reading this paper (http://hci.ucsd.edu/102b/readings/WeirdestPeople.pdf only the first two pages are the actual paper), I'd say that a lot of behavior in different cultures would be legimitately called "insane" in ours.
And besides that paper, there's also this meme flying around that "schizophrenics used to be shamans", although I don't know how believable that is.
Anyway, my point being, even insanity isn't exactly definable. Although I do agree stuff like a rabies infection, extremely severe aggressive and psychotic disorders would likely be considered "insane" in all cultures.
In the first case you would severely irritate the skin and end up with noticeable medical problems. Which IMO is a reasonable line for sanity in terms of day to day impact based on belief vs reality.
That said, sure there is something of an exception for religion.
Are you really suggesting one's social environment has no effect on one's social behavior? Because that is obviously false.
