You probably know Casey Dellacqua's name from her impressive doubles career. The Australian is ranked No. 14 in the world, and has won seven doubles titles as well as contested three Grand Slam finals (with Ashleigh Barty). You may also know the 32-year-old Australian as the mother Margaret Court pointed out in her argument against same-sex couples raising children.
Now, Dellacqua has something to say as Australia is conducting a poll on whether to legalize same-sex marriage. Same-sex marriage is legal in 24 nations, including the United States, United Kingdom, Mexico, Canada and New Zealand.
