I never realized that this term could be taken as being a little bit racist. I guess I never realized that people were prejudiced against the Dutch in the first place.
I guess I always thought it was more to do with the fact that the Dutch invented gin and alcohol in any form is known to loosen you up a bit. So, you could just as easily call vodka Russian courage. And maybe it started out like that, but that people eventually just called every kind of alcohol Dutch courage, because word use often gets corrupted like that.
I never know, after learning this kind of thing, if I should continue using the phrase. I don't want to offend anyone, but it gets to the point where you can't say anything at all without somehow offending someone.
