Misigony in fandom: Why can't little boys grow up?

I don't believe it is any more prevalent amongst fandom than amongst the general populace, just that fandom combined with the internet makes people think it's OK to express opinions they would normally not.

I believe the problems are down to a combination of factors including

1) History
sexism has been around for a long, long time
the young media of video games and American comics have been primarily targetted at adolescent, straight, white males since creation so have a primarily white male audience. as do some areas of fan interest.
This is the only thing that makes the associated fandoms different from society in general

2) Ignorance and the internet
it is said that "a little knowledge is a dangerous thing" because people with a little knowledge often think they know a lot more than they actually do know and get things badly wrong. Thanks to the internet a lot of people have access to a little knowledge.

3) Fear, especially the fear of change
American comics and video games are growing up to become closer to other media, subject to the same criticisms as other media, diversifying to reach a wider audience - and some of the established audience are confused and panicking.
they fear the diversification will remove what they like. They consider any criticisms of what they like to be "personal insult"s. Video game fans don't want proper criticism of video games - just a couple of paragraphs followed by an inflated score.

4) "Us and Them" menatlity
some (a vocal minority) within fandom gather into groups ("us") and label other people in groups ("Them") which they can use as ad hominem arguments. They pretend every person they put together has an identical extreme position (for use in strawman arguments) and then adopt an opposite exteme position. They don't bother paying any attention to what any of "them" are saying and instead place blind trust in the words of any of "Us" perpetuating misunderstandings.

That's a good point, misogynistic and misandric practices tend to be a result of more than just the fandoms they belong to. I'm a fan of the James Bond franchise, but I definitely don't ascribe to applying his rather outdated attitude towards women to my own life.

Agreed. Misogyny is, unfortunately, rife in many social and professional settings. Although much of it is more covert nowadays, it's still very much prominent.

Misogny's a very strong word, though, isn't it... Anyway, you get tons of people like it in the real world not just in fandoms. Then again, you get people do the opposite and use incredibly sexist and racist people who go around saying that white men sexually assault them because they have a different opinion.

Hmm, I'm probably a sexist, i'll admit it. I think there are things I do, that a woman cant do, but there are also things I do that most men cant do either. I'm literally a monster. 6'4 400lbs and only a 9 percent fat in my bmi. In my younger days I could toss around a 350lb dead hog like it was store mannequin. I'm freakishly stout. When it comes to my job, i have no problem with women doing the same job as me, for the same pay.

I will open the door for a woman, where i might not for a man, i show women more respect than i do men, in the real world. Probably due to the fact that my mother raised me to respect everyone, but especially women.

I am dreading the day that the doctor turns into a woman. Though, i will give it a chance. (on a side note, i wonder why there has been no talk about the doctor changing race, instead of gender, imagine a Chinese looking doctor, or a doctor of any other color, other than white, what if they kill 2 birds with one stone, and make the next doctor a black woman?)

I will also say that, making Thor a woman, made no sense, making Johnny Storm a black man in the last movie killed the movie, and you don't throw away years of history, in fandom, just for diversity's sake, it has to fit into the story, cause i hated miles morales as the new spider man, but way back in the 90's when they 'killed' Frank Castle, i really enjoyed  the woman who replaced him. I hate Dakken, but love Wolverine, and i enjoy x-23, it's all about the story, and having the story make sense, instead of just, hey, the fantastic four are all white, and only one of them is a woman, we need a mandatory minority, that's crap. Just like the FF cartoon in the 70's with Herbie instead of Johnny Storm.

Good thing about BF, i haven't heard any real crap yet, hopefully i wont.
