@SuperOniichan I mean, yuri is a pretty broad term. It doesn't just refer to romantic relationships. As long as the story focuses on a strong emotional relationship (best friends, bitter rivals, lovers, ect) between two girls, it's yuri. I get really annoyed when I see the Shoujo Ai tag, because pretty much all of that is also yuri. Thanks to the weird made-up distinction that was made when the term became widely used in western countries, I have to look at two tags to find this shit when it really should just be under one.
So yeah, it's not just shippers reading context that can make that stuff yuri, it very much is yuri as long as those feelings of friendship are strong enough, and the story puts enough focus onto it.
