As designers that care about social issues, we must remember that we have strength through out position in the industry. From our choice in vendors to our recommendations to clients - our voice can collectively be heard through the objects we design, the environment we affect, the messages we communicate, the clothes we make and the images we create.
Its not what is being said as much as how it is being said - and that is 100% in our control. Our work is everywhere and the audience is large. We don't need "neon signs" to communicate our message, no, our tools are more subversive than that!
Use the "how" to effect change in a sublime way.
