I don't really understand the shock and horror I'm meant to be experiencing here. If you're ok eating boiled egg, and ok eating cooked chicken, I don't really see the issue. Certainly more palatable than raw egg, in any case.
Not sure what is supposed to be controversial about balut. The article reads like an American boy experiencing another culture as a gross thing you do on a dare with some wikipedia bits mangled in.
When I used to play poker at Bay 101 in San Jose, a favorite (faux) joyous occasion when winning a pot (or talking about getting someone to fold so I could win the pot) was to relish the balut I would order with the winnings.
