Feminism is absolutely necessary. Its plain as day. I can see it in your responses, throughout the gaming community, throughout society as a whole.
First of all, let's dispense with the feminist strawman already. Feminism is not here to take over and oppress men. If you want to look for radical feminists that want to kill all men, sure you can find them. Because you know what? There are radical people for every movement. But bringing it up every single time feminism is brought up is ridiculous. You're shutting the conversation down before it can happen. ( Not sure how many here are Christian, but if somebody brought up the radical sects of Christianity to you every time you mentioned your religion I'm sure you'd be pretty pissed off. )
We are still a long way out from actual equality. The arguments people today use against feminism are the same arguments men used against feminism 100 years ago. You want to think we're all equal but we're not. Until we can all acknowledge our privilege and work toward a better future we're going to be stuck in inequality for a long time.
Women are treated as objects. Its clear the way they're presented in the media and the way people talk about or to them. I'm sure all of you wouldn't feel good if your entire life was people judging you as a sex object. If you're sexual, you get called one slur, if you're not sexual you get called another. There's no winning there. For a man, it doesn't matter. That's called a double standard which wouldn't exist if we were equal.
Women are treated as less intelligent or less qualified. Would you feel good about going through life trying to pursue a career and are constantly questioned, talked down to, and having everything explained to you while a person of the opposite sex does not?
Nobody is saying as a white man you haven't had challenges and adversity in your life, but typically for women and people of color your have to work twice as hard to get half as far. People have socially constructed images of how they view certain types of people to be and its hard for many to get past them.
On the topic of 'shaming white men'. White men have ruled for a long time. The institutions that exist within western society were created and controlled by white men. Most wealth is owned by white men. Laws were made by white men. Historically its a very unequal world. This is not about shaming white men. It's not about calling them evil. It's about exposing the privilege they enjoy each and every day so that we might start getting the conversation going as to how to change the world.
It's easy to say "Hey, they should take down the confederate flag, see I'm not racist!" It's not as easy to understand and admit your privileges and biases.
The 'everyone is to sensitive these days' argument is bullshit. You don't want to admit that these things are ingrained in society and that maybe, hey, you're a little bit sexist/racist/homophobic/etc too. Its easy for a bunch of white men to sit around and go "Yeah I agree that's not offensive, these people are too sensitive!"
Your experiences != everyone else's.
