And Japanese are short, can't speak English, too ?
We don't eat whale at home, never have, nobody we know eats whale, neither can you see whale on display as a matter of course around you in Japan. Sure, you can find it if you want it. Also, even children as a rule can usually explain what a whale is, and how is different compared to, say, tuna or mackerel. Schools are a wonderful thing.
That said, your other point is quite apropos on the massive hypocrisy in general when it comes to meat and fish consumption.
The horrific process that brings chicken or beef to people's plates would be something to consider way before looking at whaling.
( Edit : Not vegetarian or vegan, by the way. )
( Edit 2 : And for clarity's sake : Not in favour of whaling for any reason, myself. )
