It is possible to build a better society, but we have to be vigorous. For awhile we were moving towards a less racist society, at least in the United States. Perfect? No. But much better than the past, and most people disapproved of racism. But then something happened. The racists basically starting promoting their rhetoric, implementing policies, and changing the curriculum in schools to promote racist ideas such as favoring certain races over another. Everything that was done previously was undone over time. So even though we can move forward, we can also move backwards.
