There has been a debate for a very long time over whether gay people choose their sexual orientation. A study by Simon LeVay did a study in 1981 examining the brain of homosexual and heterosexual men to examine any slight differences. His findings show that the neurons in the hypothalamus are less than half of the size in gay men as compared to heterosexual men. While there were a few criticisms of LeVay's study, however newer studies have shown that the hypothalamus plays a key role in one's sexual orientation. People that believe homosexuals are choosing their sexual orientation are backed by very little scientific evidence and are typically raised in families that have negative feelings towards gays. Personally, I believe that gays cannot choose their own sexual orientation and are born that way. I have developed this viewpoint for myself through experience with friends that happened to be homosexuals and stating that from a young age they knew they were different from other boys. There is a significant amount of evidence that shows homosexuals did not choose to be the way they are to convince any rational person in my own opinion.
