Why should I be donating money to people who I don't give a fuck about?
It's not something that you are forced to do. You can chose to If you feel that it's a good cause.
You might not give a fuck about the man who's lying, in an empty street you happen to be passing down one day, crying out for help because he's fallen and broken his leg. You might indeed not care about the man, or who he is - but I'll almost guarantee that you'll call for an ambulance with your phone or lend him a supporting shoulder to the nearest emergency station. When faced with the decision of helping that man you'd probably do it, and so would almost anybody, because it benefits society and humanity.
That's a bit how I see it. You have the chance to help that man, even though he might just be a nobody.
I don't expect anyone from Haiti to be donating money to save my ass if something happens where I live, so why should I do something for them?
I'm sorry to say this but I don't know whether or not you're being serious. Haiti is one of the poorest countries in the world. 80% of the population of Haiti is estimated to be living in poverty. Most live on less than 2$ per day. So no.. I'm afraid they'll have to keep those money for themselves If they want to survive.
