Also a commit on the same post, please. The same question and here is his repy:
Some of the historical factors that shape the development of individual and group indefinity involving race, class, and gender are slavery, segregation, and the industrial revolution. Slavery had a huge impacts on racial identities, Obviously slavery is not around today, but some people still think that certain races are superior to others. Segregation is kind of in the same boat. Generations of people that were segregated hundred of years ago are still affected by it to this day. And the industrial revolution has affected certain groups of people by introducing specific types of work in specific places, which goes back to what I said about segregation.
Some of the contemporary factors that shape the development of individual and group indefinity involving race, class, and gender equality, technology, and immigration. Gender qualify has led a lot of women into different roles of society over the course of the last 100 years. Technology has also shaped people and group identities. Just from people meeting new and different people online, and the different ways that people act online compared into person. And lastly, immigration and the patterns immigration have led to different races, religions, etc of people being grouped of with each other in society which makes group identities.
