Sorry but without listing the businesses, this comment is unhelpful to the point of almost being dishonest.

Every single thing exists in this world. Good and bad at every level. But outliers are no important, the middle of the bell curve is what matters most. Who actually owns these 'small businesses'? Who are their suppliers and who owns them? You have to actually do the math and figure out who is actually being affected most.

From what I've seen in the manhattan so far its been mostly large scale, corrupt companies that pay low wages and have massive profits.

If you are actually standing by the protesters and understand that looting and property damage can be valuable tool then make a map of the most of corrupt, predatory businesses in the city and circulate it. Otherwise you're actually just siding with the massive corporations and helping them maintain a violent status quo.
