many women would risk their lives to stand up for the right to vote. in your question, you said people, however, men have always been able to vote but it was women, e.g the suffragettes, who have been unequally treated in the past, present, and maybe even the future because there will always be those people who disagree.
many women risk their lives for the vote mostly for their children, and their children's children and so on. when these women take on the role of fighting for the vote, they are always aware that they may die, so they have fought for future equality, not always present equality.
