This is the most important sentence in the whole article:
"As for HB 757, [Gov.] Deal has until May 3 to decide whether to sign or veto it."That's over a month from now, people, and that's plenty of time to do any or all of the following: get out there and write to Gov. Deal (politely and respectfully, please

), contact the corporations which have spoken out against the bill and ask them to put their money where their mouths are, contact GA legislators and show them (nicely) who we really are.
And if you have the time, contact groups which are organizing direct action in Georgia and ask how you can participate.
