Not to answer for him, but there’s no inherent reason why someone inclined to do one type of community service is required to others, if he so views what he does as community service. I mean - a guy who works at a soup kitchen isn’t failing to do community service because he doesn’t also pick up litter. So I don’t see how the homeless shelter criticism invalidates his claims. You could say his time would better serve the community that way - but they have no logical connection outside of that.
That’s more or less what I figured. A group can’t be everywhere all at once doing everything. I was wondering if there was a specific reason why some activities like that might be singled out or why other activities might be included.
