All your points are well made. However, this woman was at a walk in clinic seeking medical attention for her son, so respecting that she was his mother, she clearly thought that his illness was serious enough to seek immediate medical attention. Her hateful comments were delaying his medical attention. You are absolutely correct about being careful about having the state intervene in how parents raise their children, but do you really believe based upon her racist rant, delaying medical attention for her son because of her own unreasonable prejudices,  that this mother is providing a positive beneficial, healthy environment for her son?
