When you do not fight for justice for everyone, you stand for justice for no one.
We cannot stand for racial justice without standing for gender justice because people of different races are also gendered.
You cannot fight for gender justice without standing for QUILTBAG justice, because women are also sometimes lesbian or bi or queer.
People cannot stand for QUILTBAG justice without standing for economic justice because sometimes trans* and queer folk are poor, often more poor.
They cannot stand for economic justice without standing for disability justice because sometimes the poor have disabilities.
I cannot work for disability justice without supporting racial justice, because sometimes the disabled are black and brown.
Do you want justice? Then want justice for everyone. The fight is not either/or it is all or nothing. Equality is a state of being, not a race to be won.
Justice is not a prize to be hoarded if it is to mean anything at all.
Quit telling people to sit down and be quiet in favor of your cause. Their cause is your cause.
