I voted yes.
There's this funny thing going on called 'globalisation' that reaches into everyone's lives. It lets you buy cheap ****ty products from China that you don't need, it lets you talk to your long distance partner on Skype, it enables you to peddle your wares on a global scale and in doing all those things it brings people together. But unfortunately, sometimes an element of that system, whether a good or a bad element, backfires. When that happens, it's not on for people to suddenly return to an isolationist mindset and say, 'well, they can just help themselves out,' because unfortunately the world does not operate that way any more.
An element of all this is that (obviously) capital is highly mobile. Whether people like it or not, the financial interdependence of the world nowadays is such that a crisis in one place equals a crisis everywhere. Let me go on the record and say that the Greek government (whoever was running them over the last decade or so, both right and left parties) was stupendously stupid for running up a huge deficit and debt and I don't condone that in any way. However, they have created a malignant cancer. If it's not cut out, it's going to spread. It is simply not enough for people to say "well, I don't like that there's a cancer, so I'll just let it remain," in the hope that things will magically get better.
The argument against the US bailouts was premised partly on the idea that if a corporation stuffs up, it should be made to collapse. No moral hazard, no bailouts. However, what we are dealing with here is a government, NOT a corporation. And last time I checked, the business of governing in itself was not an element of a free-market system. But one thing is clear: financial markets have taken a look at Greece's problems, and they are not liking it.
Look at the level of fear worldwide when Greece had its credit rating downgraded. People know that Greece is not the only problem country: all the PIGS countries are at risk. The cancer could easily spread. The only response if we allowed to Greece to default on its debt would be more fear, more economic strife. If such a thing were to occur, the problems for the other PIGS countries would multiply and the situation would only get worse.
So there are two choices: don't authorise a bailout, and open the door to the possibility of yet another financial collapse. More unemployment. More wealth lost. And I bet that would leave the people who stood there, middle finger raised, telling the Greeks to **** off, looking pretty silly. OR: bail them out (even if this in itself is not exactly an ideal solution) and stem the risk; cut out the cancer. It makes sense to me.
