February is LGBT (Lesbian, Gay, Bisexual, Transgender) History Month, which aims to promote equality and diversity by increasing the visibility of lesbian, gay, bisexual and transgender (LGBT) people, their history, lives and their experiences. It promotes awareness, safety and wellbeing, and can be a time to learn about Nazi persecution of gay people.
