Boycott Wal-Mart! Protecting safety of customers and employees from medical marijuana users?

Consider sending a message to Wal-Mart that it is not ok to fire medical marijuana users.

Message sent from here to Wal-Mart,

I'm not happy about your actions towards legal medical marijuana users who happen to be Wal-Mart employees. See the link. I will no longer shop at your stores and I will be asking others to do the same. Unless I hear that Wal-Mart has changed their policy on medical marijuana for employees with a valid prescription. It may be within your legal right to terminate employees who use medical marijuana but it does not make it right! We will use our legal right to boycott. I ask you to do the right thing for medical users. Change your policy.

And Wal-Mart's response:

Dear Mike,

Thank you for your recent inquiry. This is just an unfortunate situation all around. We are sympathetic to the former associate's condition but, like other companies, we have to consider the overall safety of our customers and associates, including the associate involved, when making difficult a decision like this.

Sincerely,
Walmart Customer Care

Safety of customers and associates? What? Are these folks at Walmart all on hardcore prescription meds? Apparently so.
