oh, that’s weird. i thought it those things change because people vote for laws that change those things.

People didn't vote to end slavery. There were whole wars about it.

Also women didn't earn the right to vote through voting.

The seed for the first Woman's Rights Convention in the United States in Seneca Falls, New York, was planted in 1840, when Elizabeth Cady Stanton met Lucretia Mott at the World Anti-Slavery Convention in London. The conference refused to seat Mott and other women delegates from the U.S. because of their sex. In 1851, Stanton met temperance worker Susan B. Anthony, and shortly the two would be joined in the long struggle to secure the vote for women in the U.S. In 1868 Anthony encouraged working women from the printing and sewing trades in New York, who were excluded from men's trade unions, to form Working Women's Associations. As a delegate to the National Labor Congress in 1868, Anthony persuaded the committee on female labor to call for votes for women and equal pay for equal work. The men at the conference deleted the reference to the vote.[22] In the US, women in the Wyoming Territory were permitted to both vote and stand for office in 1869.[23] Subsequent American suffrage groups often disagreed on tactics, with the National American Woman Suffrage Association arguing for a state-by-state campaign and the National Woman's Party focusing on an amendment to the U.S. Constitution.[24][25][26]

One major division, especially in Britain, was between suffragists, who sought to create change constitutionally, and suffragettes, led by English political activist Emmeline Pankhurst, who in 1903 formed the more militant Women's Social and Political Union.[47] Pankhurst would not be satisfied with anything but action on the question of women's enfranchisement, with "deeds, not words" the organization's motto.[48][49]

Power will never be freely given. Anger creates movements, movements create action, and action causes change. I'm not saying voting isn't part of the equation but not in the way you think it does.

Sure, black slaves were given equal rights because they politely asked and then white people simply voted for it!

John Brown was first and foremost outraged by the lot of his fellow humans. That anger pushed him to act. Same goes with the British revolution, the American revolution, the French revolution and the Russian revolution. Outrage, anger then action.

So are love and anxiety in ways.
