I see I was looking at the conversation from a wider perspective and likely misunderstood the context added by the image. I don't disagree with your comment "abolishing 'x' ends 'x'". However, abolishing any given inequity, one at a time, in one area at a time is not the progress I was speaking of when I asked how to change social structure. Before we can abolish anything, we need people who believe it should be abolished, and we need enough of them to institute change. My question was directed more toward the earlier steps: identifying necessary change and then creating/maintaining a movement which can enact that change.
