Introductory Paragraph

My goal is the introduction.

As history has shown us, the only certain thing is change. There was a change when slavery was abolished, and a change when women got the right to vote. This same type of change is also seen today, with actions such as gay marriage. And all of this change is eventually understood and accepted because all people deserve equal rights, but the difference between now and then is the root of sexuality. Gender and race have always been large issues, but sexuality has only recently become a mainstream argument. Gays are now searching for new laws to be passed on their behalf, and most of all, want to be treated as equals. Between religion, science, and the government, homosexuality has become a new topic for debate in the United States. Of course the biggest interest to mainstream media related to the topic is what causes this change in sexuality. Between religion, science, and the government, homosexuality has become a new topic for debate in the United States. Many scientists argue that genetics is the main determinant for homosexuality, and I have mixed feelings about it. On the one hand, biology probably has a large part to do with sexuality. On the other hand, the environment of an individual may also change a person's preference. Because both arguments have such great evidence, many would agree that sexuality is a combination of both.

I finished drafting my introduction. I need to move onto my first main body paragraph about biology.
