Ask Slashdot: Why Do So Many of You Think Carrying Cash Is 'Dangerous'?

An anonymous reader writes: Recently, I asked Slashdot what you thought about paying for things online using plastic, and the security of using plastic in general; thank you all for your many and varied responses, they're all much appreciated and gave me things to consider.

However, I got quite a few responses that puzzled me: People claiming that paying for things with cash, and carrying any amount of cash around at all, was somehow dangerous, that I'd be "robbed," and that I shouldn't carry cash at all, only plastic. I'm Gen-Y; I've walked around my entire life, in all sorts of places, and have never been approached or robbed by anyone, so I'm more than a little puzzled by that.

So now I ask you, Slashdotters: Why do you think carrying cash is so dangerous? Where do you live/spend your time that you worry so much about being robbed? Have you been robbed before, and that's why you feel this way? I'm not going to stop carrying cash in my wallet but I'd like to understand why it is so many of you feel this way -- so please be thorough in your explanations.
