The issue of personal safety is almost always overblown. The difference between the best part of town (i.e. where you feel comfortable) and the worst part of town (where you are uncomfortable), anywhere I've ever been, has been at most a relatively small degree. The perception of the issue is almost always caused by the "not fitting in" part.

Further, career stresses are frequently underplayed in the tech environment. Certainly, I would feel very little worry about saying, "Adios, and I'll leave my badge on my desk on my way out." On the other hand, if you are not part of the tech culture and everyone you know is either unemployed or working, say, outside the tech field, the potential of being punished simply for standing out is a bigger worry than I suspect you really think.

In other words, it isn't the same thing, but it's not as absurd as you might believe.
