So what if you build your soup kitchen in a spot that ends up benefiting one group more than another (say it is closer to where they live)? Is it then taboo to notice that and consider moving the kitchen?
Build it where there's the most hunger and avoid the issue completely.
If the discussion is towards feeding more people, then yes move the kitchen. If the discussion is about equality quotas, dismiss it and move on. Almost all race-based charity could be targeted at the poor and actually reach the same people, but it hurts everyone to dwell on that fact.
The real problem with "X" based charity, where X isn't "need", is that they adjust slowly to the changing landscape. And they waste money on the needless question of who to help rather than helping anyone who needs it.
