The history of the gay rights movement has been a hard fought battle within the United States. In fact the first gay rights movement dates back to 1924 with the creation of The Society for Human Rights in Chicago, Illinois. It wasn’t until the 1960’s that gay rights started to make progress. In the year 1969 The Stonewall Riots took place when gay, lesbian, and transgender patrons of a New York bar were raided by the police. This forever changed the movement from isolated incidents to a world wide phenomenon.

The quest to find a biological substrate for homosexuality resembles an earlier movement in research to determine the nature of I.Q. scores. Both revolve around finding a biological basis for differences in human behavior. Like the previous research on intelligence, the research on homosexuality is plagued with difficulties. One large obstacle in this type of research is the difficulty in making statements about causality from correlational studies (simple, linear relationships between two variables) (4). In other words, it is difficult to determine what comes first the chicken or the egg.
The concept of sexual orientation, which is a person’s romantic and emotional attraction to another person, is a modern sociological construct (Macionis, Jansson, Benoit, & Burkowicz, p. 190, 2016). The predominant classifications of this concept are heterosexuality, meaning the sexual attraction to someone of the opposite sex, and homosexuality, the sexual attraction to someone of the same sex (Macionis et. al., p. 190, 2016). With the large majority of society’s acknowledgment towards these two sexual identities, it leaves little to no room for those who find themselves in neither ends of these categories, to receive any sort of recognition. More specifically, the visibility for those who establish themselves as bisexual, defined as the sexual attraction to people of both genders, face misconceptions from a portion of society (Macionis et. al., p. 190, 2016). Whether it may be from heterosexuals or homosexuals, someone who falls in between the two identities seem to encounter greater difficulties in gaining social acceptance. Despite having its place in the term, LGBTQ, which is an abbreviation for the community of lesbian, gay, bisexual, transgender, queer, and people of other sexual orientations and
The LGBT (lesbian, gay, bisexual, transgender) community has been disapproved by many since it first came about in the 1950s. Since then, the societal attitude towards homosexuality and LGBT culture has changed greatly, as much of the world has become more accepting of same-sex sexuality as it has become more common. Studies have also shown that the younger generation are more tolerant towards LGBT views. The LGBT community consists of many beliefs and values that make the community different and intriguing.
Homosexuality has always played a huge role in society. Views on this topic have changed immensely from the beginning of the greece era to now in modern society. People have become more appalled with this topic because now in society there are stereotypical views on “normal” ways of living. Religious views have also impacted people's decisions and thoughts about it.
A 2001 study by the Kaiser Family Foundation revealed that more than 76% of lesbians, gays, and bisexuals believe that there is greater acceptance of their sexual orientation by the general public (Wellner, 2001). The survey also revealed that 73% of Americans believe that laws against hate crimes should include crimes against homosexuals and bisexuals, while 76% would support extending discrimination laws in employment to protect diverse sexual orientations. Wellner (2001) noted that support for “legally sanctioned gay and lesbian marriages appears to be increasin...

There is abundant evidence that brain size and structure differences can result in homosexuality. Brain scans conducted in Sweden show that straight male’s brains are similar to lesbians, and gay male’s brains are similar to a straight woman. These similarities are in shape and structure, and a reflection that they function in a similar way as well. Key parts of the brain that control anxiety, aggressiveness, and mood are similar in homosexual males and heterosexual females, same with heterosexual males and homosexual females (Roman). A study published by the journal Science in 1991 showed that the hypothalamus was twice as large in heterosexual men than homosexual men. The hypothalamus of the brain controls the release of sex hormones. Also, neurons in INAH3 are packed more closely together than in straight men (Malory). However, science is yet to determine if homosexual practices change the brain or if the brain results in homosexual practice (Deem).
