Gentlemen Prefer Bimbos

Often times I have my children read a book for our literature class or because it won an award or it was highly recommended.
Many times it starts out with a book they do not like from beginning to end.
Other times, they get to the middle of the book and they are already on our local library's website looking to check out other books from the author.
I decided if I have to "make" my children read selected books maybe I should too. A very funny author suggested the book Gentlemen Prefer Blondes by Anita Loos.
I am half way through the book and I can't like it.  All the spelling errors is driving me BANANAS.  Every time I come across one, I have to read the sentence and try to understand what she was trying to say.
Do "gentlemen" just prefer women who are so unintelligent that they feel good about themselves?

Please forgive my misspellings and grammatical errors from this brunette. :-)
