Slavery, Freakery, Feminism, Homosexualizm, what's next?

When learning and talking about each of these three topics individually, it's hard to notice the trend but when going back through all of my notes I couldn't help but to notice this trend. In the U.S., we first started with slavery, making Blacks the minority almost as if they were not even humans, completely unequal. Once slavery began to end and blacks started to become integrated into society, still with inequalities but becoming more 'human-like', freak shows began to emerge. Freak shows were dehumanizing somewhat like Blacks during slavery, both of these notions were essentially for the entertainment/help of U.S. white citizens. Once Freaks became people with psychological problems, they were rejected by the U.S. population. Also around the same time as freak shows came feminism, this idea that women were now speaking out about inequality, almost like the slaves and freaks. Now women were fighting for their rights, fighting out against men. Once all of these problems were essentially 'solved', Homosexualism began, people fighting out against gays and lesbians. Now homosexuals had to fight for their rights, fight to be an equal part of society. Today homosexuals are still slowly gaining their rights in order for full equality. However, in society today I feel that each of these types of individuals (Blacks, Freaks, women, and homosexuals) are still trying to become completely equal to white straight males. Will all individuals in our society ever be truly equal? If not, I wonder what will come next, who else can our society point the finger at? I am definitely interested in this notion, and I personally would not be able to imagine what type of individuals will be in the light next, if any.
