Lawrence's Share of the class disgustion

I read chapter 24, A Woman Named Truth.
I read that she was a really tall black slave woman that had a lot of pride and dignity. When she heard someone making a public speech on how woman were weaker and inferior to men, she argued and spoke loudly. she told the man that she was as powerful as any man and could eat as much too. She had told the crowd that she had endured hardships that they couldn't imagine, such as crying as she watched her children being sold. this speech put tears into the listeners eyes and made them favor her. As a slave Sojourner was treated badly and soon she ran away and tried to buy her children back, but before she could, one if her children were sold, which was illegal. Sojourner Truth found a lawyer, went to court and won her child back. That told her that the court was fair and could be trusted. Isabella was her real name but she changed it to Sojourner Truth to celebrate her freedom. With her she traveled and fought for truth and justice. When she spoke people would listen and when she spoke she wore a banner that said, "proclaim liberty throughout the land onto all the inhabitants there of", which was also written on the Liberty Bell. throughout the rest of her life, she fought for womans rights and for black rights.

These are the details i read about her and i noticed that she was a very strong woman and had a powerful voice. I really cant connect this to anything I know of in todays world though.
