These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Although the Proposal was more of a jab at the English. It was a parody of the attitude of the day: let's strip them of their rights, steal their land, burn what they have left, then whine about how poor and lazy they are.
