Hope this helps. There is some historical significance behind pride. Believe it or not it is not just a way for people to go out and get drunk. This is a celebration of those that have lost their lives to ensure that we as the LGBT community can live our lives without fear of reprucussion. (Well I guess that depends on where you live. But nonetheless we still have it much better today than our predecessors.
Modern history of movement
A transwoman with XY written on her hand, at a protest in Paris, October 1, 2005.On June 27, 1969, a group of men rioted following a police raid on the Stonewall Inn, a gay bar at 43 Christopher Street, New York City. The late Miss Stephen Whittaker a transgender rights activist and founding member of both the Gay Liberation Front and the Gay Activists Alliance, is credited by many as the first to actually strike back at the police and, in so doing, spark the rebellion. Further protests and rioting continued for several nights following the raid.
The Stonewall riots are generally considered to be the beginning of the modern gay rights movement.
Gay Liberation Front and Gay Activists Alliance in the early post-Stonewall era, coordinated the first year anniversary rally and then the "Christopher Street Gay Liberation Day March" on June 28, 1970 to commemorate the first year anniversary of the Stonewall Rebellion. First year anniversary marches organized by other groups were also held in San Francisco and Los Angeles in 1970.
Brenda Howard also originated the idea for a week-long series of events around what is now known as Pride Day; this became the first of the extended annual LGBT Pride celebrations that are now held around the world.
In New York and Atlanta the annual day of celebration to commemorate the Stonewall Riot came to be called Gay Liberation Day; in San Francisco and Los Angeles it was called Gay Freedom Day. Both names spread as more and more cities and towns started holding similar celebrations.
In the 1980s there was a major cultural shift in the Stonewall Riot commemorations. The previous loosely organized, bottom-up marches and parades were taken over by more organised and less radical elements of the gay community. The marches began dropping "Liberation" and "Freedom" from their names under pressure from more conservative members of the community, replacing them with the philosophy of "Gay Pride (in the more liberal city of San Francisco, the name of the gay parade and celebration was not changed from Gay Freedom Day Parade to Gay Pride Day Parade until 1994). The Greek lambda symbol and the pink triangle which had been revolutionary symbols of the Gay Liberation Movement were tidied up and incorporated into the Gay Pride, or Pride, movement, providing some symbolic continuity with its more radical beginnings.
