Ah Godwin's law, internet arguments wouldn't be as stupid if it wasn't for it! Godwin's law is usually used in the context of bad analogies between an issue and the Nazi's, I think that Godwin's law should include the Communists as well! They are frequently interchanged by some people!
I usually see far out analogies to the Nazi's/Communist's, it's funny to picture them trying to implement them. It's always looks silly! It's not to say you can't learn a valuable lesson from what happened in those oppressive regimes but to create hyperbole over them just lightens those lessons!
I used the metric system in this comic because it isn't a very controversial one and it seems like a common question people in debate classes would review. While of course the metric system makes more sense than the American standard measurement system, but using our goofy ass American system hasn't really caused us any unique problems and it would be kind of a pain in the ass to get everyone converted to metric!
Though I will argue that Fahrenheit is a better unit of measurement than Celsius, while 0 and 100 are easier numbers to remember than 32 and 212, the fact it has 180 units of temperature between freezing and boiling temperature shows a more accurate description than with a mere 100 units in my honest opinion!
