People who are prejudiced against one minority group are often also biased against others, according to new research by Stonewall.
Its report, entitled Understanding Prejudice, also shows that asylum seekers and travellers are the most likely to encounter prejudice, while older people and the disabled are the least likely.
Stonewall hopes the research will also highlight its calls for the Government to extend the current provisions on incitement to racial hatred to include homophobia, following the recent murder of barman David Morley in London.
Researchers carried out in-depth interviews with 30 people from10 focus groups in London, the West Midlands and the West Country.
Stonewall hopes the report will encourage minority groups to work together.
The charity's chief executive, Ben Summerskill, said: "Sadly, there are still all too many pockets of prejudice against minority groups in Britain."
Jacqui Smith MP, Minister of State at the Department of Trade and Industry - who wrote the foreword for the report - added: "I'm pleased that Stonewall has recognised the importance of the links between different types of prejudice."
