The Pink Triangle Trust was established as a UK registered charity in 1992 – and is the only charity of its kind in the UK.

The PTT derives its name from the pink triangle, the Nazi concentration camp badge used to identify male prisoners who were interned because of their homosexuality. Originally intended as a badge of shame, the pink triangle has been reclaimed as an international symbol of gay pride and the gay rights movement.


The Pink Triangle Trust has been promoting Humanism and LGBT Rights for over 25 years.

THE Pink Triangle Trust is a charitable trust (Registered Charity No. 1015629) set up in 1992 to advance the education of the public, and particularly of lesbians and gay men, in the principles and practice of humanism, and to advance the education of the public, and particularly of humanists, about all aspects of homosexuality.

It may also assist individuals to obtain remedies under the law where they have suffered unlawful discrimination on account of their homosexuality or their Humanism.

The Pink Triangle Trust is:

• A member of Humanists International

• A member of the Cutting Edge Consortium

• A member of the Alliance for a Secular Europe

• A member of the Secular Policy Institute (SPI), a think tank organisation of thought leaders, writers, scholars and speakers with a shared mission to influence public opinion and promote a secular society. We believe governmental decisions and public policies should be based on available science and reason, and free of religion or religious preferences.

• A member of the International Association of Atheists.

The Pink Triangle Trust has the following trustees:

• Stephen Harvie (Chair)

Diesel Balaam (Treasurer)

• Stuart Draycott.

Nigel Jones is a healthcare professional working in the UK. He has been a member of GALHA (Gay and Lesbian Humanist Association) since the late 80s and, from 2012, LGBT Humanists UK.

The primary aims of Nigel’s Trusteeship are:

1) Promote humanism and secularism. Laws should be based on common sense, ethics and reason rather than on religious scripture. Religious laws relating to “blasphemy”, “apostasy” etc have no place in the 21st Century

Dean Braithwaite

2) Promote human rights—especially the right to live openly as a homosexual. This is a fundamental right, which is still not possible in many parts of the world (illegal in 81 countries).

3) To fight discrimination on the grounds of sexuality/ non-belief. Gays and atheists in a large part of the world are too often discriminated against and even face capital punishment. This must be stopped.

Our principal Aims

The PTT’s principal aims, as set out in its Deed of Trust, are to promote the principles and practice of Humanism to the public, and particularly to lesbians and gay men, and to advance the education of the public, and particularly of Humanists, about all aspects of homosexuality.

Humanism is essentially a system of thought that rejects religious beliefs and centres on humans and their values, capacities, and worth.

The PTT may also assist individuals to obtain remedies under the law where they have suffered unlawful discrimination on account of their homosexuality or their absence of religious belief.

In 1990 the PTT started publishing a quarterly magazine, the Gay and Lesbian Humanist, which featured national and international news, feature articles and reviews. Regular contributors included journalists in the UK and abroad writing for the lesbian/gay and humanist press. The magazine was widely distributed to gay, lesbian and Humanist organisations and stocked by gay and alternative bookshops in the UK.

In 2012 the PTT launched an online magazine, The Pink Humanist, but ceased publishing it when our new blog was created in the spring of 2019.

In 1996 the PTT started arranging secular ceremonies of love and commitment for gay and lesbian couples as the alternative to Christian “blessings” arranged – usually clandestinely – by gay clergy. The PTT ceremonies were called “affirmations”. They were widely advertised, mainly in Gay Times and were soon in great demand.

A nationwide network of Humanist celebrants was established from Aberdeen in the North to the Channel Islands in the South and some donated part of their fee to the Trust. When London Mayor Ken Livingstone allowed ceremonies for gay and lesbian couples to be held at City Hall, the PTT was listed as providing them – and many of them were conducted by Denis Cobell, then President of the National Secular Society.

The provision of these ceremonies continued until the Civil Partnership legislation was introduced by the Labour Government in 2004 and it became possible for secular ceremonies to be held after registration at Registry Offices up and down the country.

For many years the PTT provided substantial indirect funding for the Gay and Lesbian Humanist Association (GALHA) when its magazine was issued free to GALHA members. It also funded the printing cost of the GALHA newsletter which was later published in place of the magazine.

It has provided funding for other LGBT and Humanist projects such as LGBT History Month, a convention of the Nigerian Humanist Movement and the Uganda Humanist Schools Trust (UK).
