Signing online petitions may do nothing, but it at least stimulates awareness among the community. If these people are pushed hard enough, they will eventually do something about it - like call their congressman, write a letter, etc. So, it's with that spirit in mind that I do sign online petitions and urge others to do so as well because, if you truly care about the issue at hand, you'll want to know more about it.

In lieu of special coding, I posted the image repeatedly in a row across the first sticky post in my journal until something better could be made available to everyone.
