Well don't forget, the money .Gov spends for Food Stamps is not donated by any stretch of the imagination - it is coerced from the productive workers and businesses under threat of force (fines, imprisonment, all all that sort of violent stuff).  Resist and they come looking for you, resist more and they will kill you.

Foodstamps and welfare are not charity, it is theft and violence pretending to be charity.  Many people pay up only due to fear of being attacked if they do not comply.  What kind of an evil system is that!

So if someone wants to donate their bitcoins for charity, excellent, please do.  The danger lay in good Samaritans taking it upon themselves to force everyone to do so in some way.  When that happens, it is no longer charity but simply evil.

This Robin Hoodesq technique of wealth re-distribution is soooo twentieth century.
