Ice-cream maker Ben & Jerry’s on Thursday said it would no longer serve two scoops of the same flavour in its Australia outlets unless the country’s politicians decided to legalise same-sex marriage – because “love comes in all flavours”. In a blog post, the company asked its customers to push their local representatives to bring in marriage equality before the next parliamentary session on June 13.

“Imagine heading down to your local Scoop Shop to order your favourite two scoops of Cookie Dough in a waffle cone, but you find out you are not allowed ” the post said. “You’d be furious! But this doesn’t even begin to compare to how furious you would be if you were told you were not allowed to marry the person you love.”

The company said its team would put post boxes at all its “Scoop Shops”, so people can write to their MPs. It also quoted a 2014 study that showed 72% of Australians favour marriage equality.

This is not the first time Ben & Jerry’s has backed a political cause. In the past, it has spoken up in favour of the Black Lives Matter movement in the United States and criticised President Donald Trump’s executive order that sought to ban travellers from Muslim-majority nations. When the US Supreme Court legalised same-sex marriage in 2015, it released a flavour called “I dough, I dough”.
