I think, whenever someone attacks a position I take, and then implies that because they proved me wrong they proved my position itself as completely wrong, it should be called a “Straw Dog”.
Oh, and on a related note…I’d like to collaborate with someone on a remake of Sam Peckinpah’s film ‘Straw Dogs’. There would be a slight alteration to the script: instead of everything there now, it would consist entirely of people challenging points I’ve made and then saying “Ha! All similar points are therefore invalid!”
I envision a budget of at least $1000.
