<human>:  How did the Women’s Liberation Movement start in Pennsylvania?
<bot>: The Women’s Liberation Movement began in the 1970s and 1980s. It was a protest against sexism, discrimination, and the oppression of women. It was started by a group of radical feminists, who were mostly college-educated white women, who felt that they were being held back from their full potential. They wanted to get rid of the social and legal barriers that were preventing them from reaching their full potential.
