June 2018 is LGBT Pride Month. Gay pride or LGBT pride is the positive stance against discrimination and violence toward lesbian, gay, bisexual, and transgender people to promote their self-affirmation, dignity, equality rights, increase their visibility as a social group, build community, and celebrate sexual diversity and gender variance.
Common symbols of pride are the rainbow or pride flag, the lowercase Greek letter lambda, the pink triangle and the black triangle, these latter two reclaimed from use as badges of shame in Nazi concentration camps.
The month of June was chosen for LGBT Pride Month to commemorate the Stonewall riots, which occurred at the end of June 1969. As a result, many pride events are held during this month to recognize the impact LGBT people have had in the world. (With material from: Wikipedia)
