There however are different arguments other than Serial killers, such as if people are born gay. This is where many people argue. On one side there are those who say people are born gay, then there are those who say people are not born gay. I take the side that people are not born gay, however in is not necessarily a choice either. Many will argue that they have been gay since they could remember, well that may be true but it is proven that a child does not know even their own gender when they are born. Instead by age two or three they start to understand wether they are a boy or a girl. This is possibly the time in life that a person becomes confused of their gender and become 'gay'. This could come from how a baby is treated from birth to this point. If a boy is treated like a girl or is raised without a masculine role model, and only see the feminine role, they could exhibit more feminine behavior. That is not saying that everyone without a masculine role model is like this, there are many who show masculine behavior as well. Many times it is the environment that a baby grows up in and the habits the baby obtains, that shows how the baby is going to be as a child, same goes for a child to a teenager, and a teenager to an adult. It is a circle that never ends, parents pass on traits and habits to their children, and in some cases they treat their children how they were treated by their parents. An example would be such as parents that abandon or neglect their children. This make it more likely for their children to exhibit the same behavior as their parents towards their children and so on. This also is sort of how rapists are born, generally if you look at the past of a rapist you will find that many of them were molested or raped themselves as children or teens, by a family member, a friend, or even a stranger. But in many cases it is shown that they were raped by someone close to them.
In summary, children are born like white, if red is added, white becomes pink. It is not possible to be born gay, a serial killer or a rapist. Generally it is something in their environment or events that happen in their life to make them that way. There are other components that are looked at such as the mental state of the person in question. Will these arguments ever be put to rest? Probably not, even if it is scientifically proven and people like myself are proved wrong. There will always be arguing about subject such as if a person is born a certain way, it's just how society today works.
