I was thinking about highlighting some excellent webcomics that are feminist and I came to realize that ALL webcomics I think are excellent are feminist, because to not be feminist is to be a bad writer in many ways. I can think of a few good comics with some bad moments, and rest assured I'll get to those when I feel like being a bit more mean and ranty, but for the most part good writers write women as people, and that's feminism.
Granted, comics that strongly feature women are more easily described as feminist. The first one that came to my mind is the excellent Liliane, Bi-Dyke. I recently bought a bunch of the mini-comics Leanne puts out and this is such good stuff. The comic deals with Liliane's life and touches on all sorts of gender, sexuality, and regular life issues, but never forgets that Liliane is real and makes mistakes, gets irrational, can be scared while being right, clever, and strong. And the humor is fantastic. But isn't that, at the end, really just good writing (and good drawing to express so much so well!)? This is a well written comic.
The Devil's Panties was just voted best slice of life comic of the year in the annual webcomics awards and boy, does it deserve it. Once again, it's not feminist just because it's written by a woman with a female main character, it's because it's written well. This is a comic where I know plenty of guys who read this and go "I identify with the lady there!". That's a tremendous sign of a) how awesome this comic is, and b) how awesome webcomic readers are. As a side point, webcomics readers are awesome. They are going to read a comic because it appeals to them, not because it's marketed towards them, and are much more likely to try out new things to find out what appeals to them. No one knows what webcomics you read! Unless you start listing ones you like where people can see it. Crud.
No Pink Ponies is another one of my favorite webcomics, but I'd probably get around to it after scores more of ones that yell out "FEMINIST!". But it is. And not because the main character is a girl who decided to open her own comic shop. No, it's because even in this sitcom-wacky, stereotype heavy comic, all the people in it are well written. The 4 nerds are, well, nerds, but their namelessness beyond the obvious physical characteristics is a funny point. (The fact that so many characters don't get names for a long time is a great running gag.)All the characters are allowed to be weird (and so they bust out of being stereotypes), or even normal. Or weird when they're supposed to be normal, like when Jess finally gets the cute (nameless) guy out on a date, he shows up dressed up as "Furreast" (aka Beast, shh!). Or even nerdier when they're already deemed a nerd.
It's that kind of writing that keeps No Pink Ponies so fresh and fun.
Now let's see to what ends I can stretch my "feminist comics" definition. What about comics I like that barely have any women in them at all? Is Penny Arcade feminist with two periphial girlfriend/wife characters and one (albiet rocking) niece? Sure, why not? It's about two guys by two guys and it's going to be awfully male, especially as most of the one shot characters from real life they're making fun of are going to be male (video game store clerks, execs, makers). The only strike against it would be that the automatic gender assignment for inanimate objects come to life is male. Div is male. So is, uh, the Fruit Fucker. Catsby, of Twisp and Catsby, could totally be a girl though. But Penny Arcade is probably streching it a bit, but it still fits, even if it can't sit down in those feminist jeans.
What about another of my favorites, Rob and Elliot, another adventures of two guys created by two guys? So far there's really only one female character, Noel. Other than that horny old lady where Elliot works. But despite the ease of keeping this one lady non-stereotypical by just adding another gal, Clay and Hampton have made her seem like she has a life outside the main characters. The comic focuses on these two guys, but it doesn't make it seem like everyone else does, too. Which is a really important distinction. So a comic entirely by guys, about guys, with barely any female presence can keep from acquiring that nasty anti-feminist vibe just by writing those two guys well and writing the woman as if she has her own life that's just not detailed in the comic.
But women reading and relating to a comic about guys is old news. What we need are more guys reading a comic and relating to the ladies. It works both ways, people! That's your feminism/equalism right there, where men and women are ultimately people. And hey, you're a people! You like stuff! And things!
In conclusion, step one of my evil plan to make people think "feminist" when they see something awesome is now complete!
(And yes, my definition of feminism may differ from yours. This just about sums up my views.)
