If "A Modest Proposal" were written today, it would be banned in most schools and libraries, and someone wouild sue... and get away with it.
In a speech class once, one assignment was to read an essay of our choice. I choose 'Modest'. Gawd did I have fun watching the guys grin and the girls almost throw up while I was reading! The teacher thought it was great. This was back in the '60's. Even then some of the kids whined that it was inappropriate (Gawd I hate that word). Hmmmm! Those kids are today's adults posing as our thought & language police... and succending!
