But is she deserving of personal attacks?
The baker has been called a bigot, a Nazi, a woman with a lesbian haircut. There have been calls to boycott her business.
If someone is highly religious and they're labelled hateful or intolerant for honouring their personal conviction, does that make them a hateful person?
Could those who demand tolerance, yet abuse someone over their freedom of religious expression, be actually described as hypocrites?
A similar issue played out in Denver, Colorado in 2012. A cake store owner told a gay couple he wouldn't bake a cake for their wedding because of his religious opposition to same-sex marriages - marriages the State of Colorado didn't recognise at that time.
Last month, the Supreme Court released its decision, siding with the baker. Two judges said the Colorado Civil Rights Commission violated the baker's right to freely exercise his religion.
They said the Commission treated the baker's case differently from similar cases involving three other bakers "for reasons that can only be explained by hostility towards the baker's religion."
This New Zealand case raises a question we must look to answer by having a reasonable and intelligent conversation - without slamming someone whose religious views deviate from our own.
Having said that, New Zealand's Bill of Rights is clear - you can't discriminate based on your religious views.
But, at the end of the day, the Warkworth baker was asked to bake a cake, not marry the couple.
