Nothing is a bigger reminder that Stranger Things is more concerned with 80s aesthetics rather than being period accurate quite like getting their lesbian character to make an STD joke. Like... I'm sorry, what?
Picture it. The year is 1989. You're a lesbian. You've moved out of your small town and you've final got other queer friends. Yet, there's one big thing impacting that community, obviously it's HIV. The media is using it to demonise the community, the government isn't helping as much as it should, and if you don't know someone who's impacted by it, you know somebody, who knows somebody, who is.
And for whatever reason, you look at your friend, your best friend, who you love dearly, who, yes, is known for sleeping around, and make an STD joke about him. Around, may I add, Jonathan who both has a gay brother and is currently living in New York.
I'm sorry but period accurate Robin would never.
