There's no shortage of sexism related to mermaids.
In a lot of folk lore, mermaids are blamed for bad storms and doomed voyages. Or they're said to lure men out to sea to be drowned.
In advertising, they're mostly ornamental. At least in these ads, the mermaids support the messaging.
The last ad in the series is my least favorite. The mermaid on the table is asking you to eat her. (Get it? Get it? Get it?) It's such a weak idea, I'm having a difficult time working up some feminist rage.
