The rally was held in what was previously considered to be a public park, Bute Park.
A police force was caught up in a freedom of speech row after its officers arrested an anti-gay campaigner for handing out leaflets at a homosexual rally.
South Wales police admitted evangelical Christian Stephen Green was then charged purely because his pamphlets contained anti-gay quotations from the Bible.
Mr Green faces a court appearance today charged with using 'threatening, abusive or insulting words or behaviour' after his attempt to distribute the leaflets at the weekend 'Mardi Gras' event in Cardiff.
A spokesman for the police said the campaigner had not behaved in a violent or aggressive manner, but that officers arrested him because 'the leaflet contained Biblical quotes about homosexuality'.
Surely this is a sign that we are well into the Interphase.
The anti-gay campaigners were first asked by police to leave the site of the show following 'complaints from the public', and complied with the request. However, they were approached again by police when they began handing out leaflets at the entrance to the park where the Mardi Gras was staged.
Mr Green refused to stop distributing leaflets and was arrested, and then questioned for four hours at a police station. He was charged after refusing a caution.
The leaflets were headed Same-Sex Love - Same-Sex Sex: What does the Bible Say?, and included a series of quotations from the 1611 King James Bible, a text usually regarded as one of the foundation stones of the English language.
The charge against Mr Green is that he used 'threatening, abusive or insulting words or behaviour within the hearing or sight of a person likely to be caused harassment, alarm or distress thereby', contrary to the Public Order Act 1986.
