I made the very same point about the long-time Leftist use of the term “wage slavery.” It was absolutely laughable to see Bashir solemnly lecture Palin about slavery, as if words like “slave” and “slavery” haven’t been used on common parlance for decades - “my husband is a slave to his job” or “I slaved away in the factory for 30 years” and so forth.
Only liberals and blacks can say “slave” or “ni**er”.
So say the speech police.
