Starbucks wants to lecture customers with liberal talking points on race.

Tell them you think George Zimmerman should not have been charged, his civil rights were violated.  TrayVon Martin was suspended from school for theft and drugs and should have been in jail, but the principal wanted his numbers to look good so they covered it up.  TrayVon Martin was on drugs at the time and beat up George Zimmerman.

Michael Brown did not have his hands up.  He rushed at the cop and this is why he was shot.

They wanted the conversation, so let them have the conversation.  When doing so, keep in mind that a number of employees agree with you but are not willing to risk their jobs by saying so.
