Wonder why the DUP don't like the European Convention of Human Rights?

"In 1975 the Northern Ireland Gay Rights Association was established to campaign for equivalent legislation for Northern Ireland. In response to the government's proposal to consider law reform, Ian Paisley launched Save Ulster from Sodomy, a campaign given a further boost when decriminalisation was extended to Scotland in 1980. The campaign was based on his belief that the Bible condemns homosexuality as a sin, which should therefore not be legally acceptable in a state founded on Christian principles.
The campaign itself was particularly linked to the Free Presbyterian wing of the DUP, and combined religious and political rhetoric. It focused on Paisley's belief in his role to save the "Ulster people" from those influences which he believed undermined their Christian beliefs and values, namely liberalism and secularism.
As part of the campaign, advertisements were placed in newspapers claiming that any change in the law "can only bring God's curse down upon our people". The group recruited 70,000 members to join the campaign mostly through outreach to church attendees.[3]
In 1981 the European Court of Human Rights, in the case of Jeffrey Dudgeon v the United Kingdom, found that the British Government was in breach of Article 8 (the right to a private life) of the European Convention of Human Rights by refusing to decriminalise homosexual acts between consenting adults in Northern Ireland. Consequently, despite Paisley's campaign, homosexual acts in Northern Ireland were decriminalised in 1982.
The DUP remains opposed to homosexuality, and in September 2004 the British government agreed to postpone a vote in the House of Commons on a Bill to provide for same-sex civil partnerships, to avoid a clash with talks aimed at restoring devolved rule in Northern Ireland. All six DUP Members of Parliament planned to vote against the Bill.[4] "
