Re "Queer"
This is not a recent phenomenon. A good many years ago (well, 43 or 44 to be more exact) my mother made friends with a woman she met at work who was an English war bride. She and her husband came to dinner and we found that she had so many strange prejudices about food that there was scarcely anything on the table she could, or would, eat. She started to explain this by saying, "Well, I know I'm awfully queer ..." but never got to finish because my younger siblings all exploded in laughter.
