I read @bustrpoindextr as not criticizing the charities directly, but rather reflect that they represent a systematic failure of government structures. We shouldn't need homeless shelters or soup kitchens - there shouldn't be homelessness or hunger. Taxation and sensible public spending should render charity unnecessary.

Which is a nice thought - I wouldn't judge people for giving their money to political interest organizations promoting solidarity rather than directly to charities.

It's a fine balance between patching the flaws of the system and trying to replace it all together. In some extreme cases charity might make the system just bearable enough that it's not overthrown, which might occasionally do more harm than good in the long run.
