Women and equalities minister Justine Greening has said the British government must "win the argument on moving forward on LGBT rights" amidst pressure on its deal with the DUP.
Ms Greening said she "absolutely" did not agree with comments from representatives of the Northern Irish party labelling homosexuality repulsive, vile and wrong.
Shadow minister Paula Sherriff had pressed cabinet minister Ms Greening on the past comments from DUP members.
Speaking at women and equalities questions, Ms Sherriff said: "DUP representatives have described homosexuality as repulsive, wrong, vile, immoral, offensive and obnoxious."
Conservative MP Philip Davies (Shipley) could be heard saying from a sedentary position that many Muslims shared these views as Ms Sherriff spoke from the despatch box.
The Labour MP continued: "Does the minister agree that it is these hateful remarks themselves that are repulsive, wrong, vile, immoral, offensive and obnoxious, and they should have no place in our politics, let alone in Government.
"The DUP once ran a campaign called 'save Ulster from sodomy', isn't it time to save Ulster from bigotry?"
Ms Greening replied: "The views that she set out are absolutely not ones that I agree with or indeed I think are shared by this House.
"As I said to her, I think it's important that the way in which we have this debate and progress continued improvements in LGBT rights and women's rights, in the rights of disabled people, all sorts of people who face discrimination in our country is in a measured fashion and where we can we find some consensus and that we steadily win the battle in that fashion."
The DUP's views on things like LGBT rights have come under scrutiny after the party signed a confidence and supply arrangement with the Conservatives to support the Government, with £1 billion of extra investment promised to Northern Ireland on the back of the deal.
Ms Greening had earlier said: "I think we have to, fundamentally, win the argument on moving forward on LGBT rights.
"This is something that needs to take place across our country, including in Northern Ireland.
"There is a democratic Northern Ireland Assembly and I think it's a debate that we all need to engage in.
"But I think it's one that we've seen progress made in over many, many years now, I think we can be proud of that, but as she sets out, there's still a lot of progress still to be made."
This was in response to Labour's Anna McMorrin (Cardiff North), who questioned whether £1 billion "is a fair price to pay for selling off these fundamental values" of equality and tolerance.
DUP MP Jim Shannon (Strangford) defended his party's stance, saying: "I have spoken with my party leader, who is a woman; my close constituency colleague and MLA, who just happens to be a woman, and my most senior member of staff, who is my most close adviser and, shockingly, is also a woman, about equality and their rights in our party.
"They seem to be satisfied, and subsequently I would ask the minister this question.
"I wonder what discussions have been held with Labour's sister party the SDLP, who hold many of the same moral issue stances that we hold, which is what I believe this question is really seeking to highlight."
