Btw, I think you meant 'animosity' instead of 'animus'. Animus doesn't necessarily mean hate, so it's kinda confusing for the people who have to answer to this poll.
Don't get me wrong, I don't want to be a part of the floccinaucinihilipilification of complex word use, but I do think that when publishing a question, you should use a clear vocabulary that won't be affected too much by the readers' varying interpretations.
I discovered the word a couple of years ago and found it to be interesting. I love knowledge and thought other IINers might like to know it too.
Nothing to do with superiority.
In retrospect using "Ideas" "Hate" might have been better instead of Ethos and Animus. And I agree that if something can be said simply, it should be.
