More than 3,000 comments have been made on the Facebook page of the Mots Café, a Malaysian eatery in Bunbury, about 170km south of Perth.
The comments were in response to the café posting an explanation of halal slaughter on its Facebook page last week.
The cafe owners had decided to explain halal after learning of a negative review telling people not to eat there because the cafe served halal food.
Some of the comments included claims Australians were being robbed of their religious freedom because they were unintentionally eating halal food because the practice is so widespread in Australia.
Other posts claimed halal slaughter funded terrorism, and the practice was inhumane because the animals were bled to death while they were fully conscious.
According to the RSPCA, under Australian regulations, all animals must be stunned before they are slaughtered under halal or non-halal methods.
But the RPSCA said there were some abattoirs that were permitted to slaughter animals without stunning them first under certain halal and kosher conditions.
Other comments on the café’s Facebook page were in support of the original post and defended the café from attacks by other social media users.
Others have questioned claims that slaughtering an animal by hand and uttering words of appreciation for its life funded terrorism or would lead to sharia law being implemented in Australia.
The cafe is the latest in a series of eateries and producers targeted by anti-halal campaigners.
South Australian dairy manufacturer, Fleurieu Milk and Yoghurt, dropped its Halal certification in November following anti-Islamic "bullying" on social media.
The company said Halal certification allows it to have healthy exports and has enabled it to be one of the biggest employers in Byron Bay.
Four 'N Twenty also decided to defend itself in the online space by explaining its position.
