I think it's a valid thought, but goddamn am I tired of the yelling from soapboxes, followed by more yelling when somebody yells back at your soapbox.
If you want to promote equality and change in games, DO IT. Promote those things by covering them and showing people what they're missing.
If you want to promote equality and change in journalism, DO IT. Provide the example. Provide the diversity of opinion that makes people notice.
But stop fucking screaming "you're wrong" over and over. Nobody's listening, that doesn't actually make a change. It draws a line and makes people angry (either because they're against you, or because they're for you and others are not). This is not a public movement. Politicians and the world are not forced to listen. It's a nerd fight, and it's embarrassing.
