Autostraddle put out a super cool article about LGBTQ representation in recent children's media. Steven Universe may have Ruby and Sapphire, but it's not the only show (or comic) to have a same-sex coded couple be represented. This was a really great article, and as mentioned, points out other media that features LGBTQ characters, probably a lot of which you'll all want to check out. Be sure to give this one a read, it's a great piece on where the future of children's cartoons and other media are headed.
