It's not intentional, mind you, but more of an over-sight by people who have designed anthropomorphic emojis, not the simple circular face ones, but the ones that look like people. Pretty much all of the many anthropo emojis I've ever seen were male gendered, no doubt just meant to be the "default" sex. But that is kinda lazy. I really liked the way the girls in this video expressed themselves. It's also kind of ironic that a menstrual hygiene product maker, Always, put out a corporate sponsored PSA that should maybe specifically mention that this is a great opportunity for designers working in .GIF and HTML code to produce and "market" lots of female gendered emojis. Overall, the PSA is kinda no big deal, except, once again, I realllly liked how smart, low-key, and self confident the girls and young women were in expressing their disappointment about this, albeit relatively minor, issue.
