I would say no for two reasons, neither of which have anything to do with race/gender/age:
1: I actually do have an issue with germs and being touched by people. I don't even really hug my family members unless it's one of those old lady relatives you don't have a choice about hugging.
2: I grew up in a big-ish city (Toronto), so I'm basically a jaded cynic. How do I know that this person doing a social experiment isn't actually about to pick my pocket when I hug them? If someone can pick your pocket in half a second when they bump into you on the street, they can surely rob you blind in the two - three seconds, if not longer, hug?
However, I did see the video ages ago of the original guy who did this (in Australia, I believe), and it was moving to see how people reacted.
