I agree, we have much bigger fish to fry, but "I don't care about this issue so nobody should" isn't how you build a coalition to get the poverty addressed. A lot of politics is "hey Gamers, remember how I got you that thing you wanted? Well now I need support as I take on a bigger, more important topic". Inversely, saying "I don't care about your problem until another problem is resolved" tends to fray the group because you're quite literally telling people you don't respect them or their needs/wants.
