Abby Martin was brave in calling out the absurd propaganda, and it cost her her job.
You don't know what you're talking about. Abby Martin did not lose her job and was not sanctioned in any way. In fact she stayed on with RT until the end of the series (the following year) after a three year run.
When the series ended, Abby left in good terms to start her own independent media venture, and to do more field journalism instead of being in the studio. She released a statement thanking RT for her time there (and likewise RT released a statement praising her.)
