This is what happens when you don't think through a problem completely.
>I'd rather donate to organizations like Second Harvest than pay higher taxes.
I'm sure you would. And when economic hard times come you'll stop donating, and the people that need it the most will kick your door in and take what food you have to live another day, even at the risk of you shooting them because they'll die either way.
Hence the argument of 'just donate' are just as unconvincing to me.
