Star Trek. For me, this was an immediate inclusion. Star Trek helped me learn to read as I memorized the credits to Next Generation, taught me about inclusion and diversity, and encouraged me to never back down.
Doctor Who. A2-D2 added this one saying that it encourages her to believe in the goodness of humankind.
Firefly. As a lifelong nerd, I've be blessed to always see strong women characters, and Firefly is an amazing example of this. Strong women, moral code of conduct (even for outlaws), and a wonderful fan group (Browncoats).
Harry Potter. This is a fandom for both of us that was instrumental to our childhood. A2-D2 write a wonderful post about the importance of this fandom which you can check out here.
We hope you have a wonderful weekend, and wish luck to those preparing to host family over the upcoming holiday. Remember to always keep it exceptionally chic and exquisitely geek!
