First, you need to research the topic of gender inequality and look for some secondary sources (scholarly writings created by known scholars) which you believe are worth paying attention to. When you will have enough information collected, with various points of view you may start the mindmapping process. Most definitely, after reviewing all the info collected you will come across some interesting arguments which you will later expand on or use as an evidence to your own claims. Only after the prelimiary research process one can generate interesting ideas, and actually can write. So go researching! As a hint you can use wikipedia and at the end of each article there is a long list of sources, which you may use. For instance, you may search: what are the roots of inequality, when did the equalization start, the role of human rights, why do the rights conflicting each other unlike freedoms, liberty and equality, why people are born unequal (we are not John Lock's Tabula Rasa ) etc. However, if this still does not encourage you to investigate further, Essaylib - one of the writing companies, can really help you with the writing process. If I were you, however, I would do it myself, as researching and writing brings much fun!
