I truly believe that Trump's election was in large part a result of a backlash against this "progressive" attitude. You can't go around screaming "racist!" "sexist!" "homophobic!" "transphobic!" "misogynist!" "you're a RICH WHITE MALE!!!" etc and expect to change people's minds. All you will succeed in doing is furthering the divide.
It's insane. This obsession with dividing and subdividing people into different identities, identifying the ones that have "privilege", and then using that as a club to take them down a few notches. The intellectually lazy tactic of using accusations of racism/sexism to shame and silence your opponents.
I think that you're not really understanding the conversation, to be honest. There's not an obsession with subdividing people into different identities because society has
already done that for ages. I've known that I was a black male (and what expectations that I have placed on me from birth because of that) since I was a little kid. Progressives didn't inform me of this - I learned by observing the way society treated people who looked like me.
What Ms. Alexander is talking about is, at the very least, giving people with identities like mine that have been foisted upon me from birth more attention. You might say that we're all human, but that's not how society works here in real life. More characters with problems that I might have specific to my identity is great! I can feel like games understand me. More characters with problems that I don't have is fine, too! I can learn more about the issues that people of other identities might be dealing with. Like, as a black dude, I know everything about white people, what they think, and what they care about because that's just part and parcel of living in Western society. I don't have a problem with this. Why do so many people have a problem with having to learn about and maybe even find a way to identify with people who aren't like them?
And the concept of "privilege" is not a way to take people down; it's merely a truth that some groups can get away with things others can't simply because of how they're born. I'm a guy, but I can walk around at night and not have to worry about being sexually assaulted as much as a woman can. I can go to a party and get drunk and not have to worry about being sexually assaulted, but women have to consider this. That's privilege. I don't have to deal with shit that women do, for example.
People who take offense at having their own social and cultural privilege pointed out to them need to get over it. If someone's response to this is to vote for a terrible human being, they are just terrible human beings who don't want their place in the social order questioned, and it's not about changing their minds so much as it is about not letting them ignore people who are not so privileged. They won't have any peace about it, at the very least.
