Hey Magellan, it's exploring time!

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.

Biological
More and more evidence is being found support the claim that genetics is a main factor in sexual preference. In other animal species, tests have determined that sexuality can be decided by altering the nervous system. This argument sides with the idea of inborn sexuality, that sexuality is handed down from your parents DNA. Some scientists have suggested that even an infection, possibly early on in life, could be a determinant for sexuality. Other claims have to do with the size of the brain, or certain areas have slight mutations.
Environmental
There are many factors outside of direct science that can a person to change their sexuality. If environmental effects are proven true, supporters of the claim that sexuality is a choice will win the argument. One of the biggest environmental effects is religion, and the acceptance of individuals based on sexuality. Most religions of the world, and many of mainstream America, view homosexuality as a sin or negative action.
Gay's Views
Most individuals that are gay claim that they did not make the choice to be gay, but simply feel as if they are born differently from everyone else. Gay's also emphasize how others treat them more so than the issue of why they are gay. Many individuals are afraid to be themselves because of what homosexuality will classify them as. First hand accounts show homosexuals as powerful individuals that have the ability to make change. Many gays also believe that sexuality is a caused by a number of reasons, both environmental and biological.
My Views
I agree that more likely than not, sexuality is determined by many factors. I also believe that there is nothing wrong with homosexuality, and that sexual preference should not hinder an individual, whether it be socially, politically, or any other issue. The ethics behind both arguments is what fuels the fire in this argument.
