Stephen Fry has labelled the DUP's conscience clause bill as "sick" and urged people to sign a petition against it.
The Democratic Unionist Party wants to introduce a new clause in Northern Ireland's equality laws that would allow businesses to refuse services to a customer if it is against their religious beliefs.
Critics have reacted angrily, claiming it is legalising discrimination, and a petition has been set up to stop the Freedom of Conscience Bill being passed.
And now it has received support from an influential backer - the gay presenter, comedian and writer Stephen Fry.
He tweeted on Wednesday: "Please sign this: once again the religious right twisting truth to present themselves as victims. Sick."
Fry has repeatedly expressed his opposition to organised religion, and has attacked church teachings on sexuality.
The Freedom of Conscience Bill was prompted by the threat of legal action against a Belfast Christian bakery business, which became know as the "gay cake" row.

Ashers is facing a court battle over its decision to refuse to make a cake that carried a pro-gay marriage slogan.
The Equality Commission, which has taken the case against the business on behalf of the customer whose order was declined, has alleged the bakery's stance was in breach of equality legislation.
Paul Givan, a DUP member of the Northern Ireland Assembly, said he believed this was wrong and wants the law to be "rebalanced".

"Gay rights, and the right to have those rights endorsed and promoted by everyone, is more important than the rights of Christians to live according to their conscience," he said.
The bill has been backed by the First Minister, Peter Robinson.
The "Stop the 'conscience clause' bill" petition was started on November 23 by Omagh woman Dervla McGaughey.
In just a matter of weeks it has gained over 10,000 signatures.
Stephen Fry was in Dublin last weekend to present Irish drag queen Panti Bliss with a People of the Year Award for her courage and defiance in fighting for freedom of expression and gay rights.
He has a Twitter following of of 8.4 million and is repeatedly named on lists of the world's most influential celebrities and LGBT people.
