the red and blue colors suggest that less is worse. Why would that be the case? It seems like it should ideally be the opposite, if anything
Do you think defending your country from invasion is worse than letting some assholes conquer your home?
Defending your country is - as far as I'm concerned - a very specific case of fighting for your country.
Also - defending a country (a more or less random historical entity with potentially largely different political and ethical views even among residents) shouldn't be conflated with defending your home.
For me the former is abstract and quite artificial. The latter is literally the place where I live.
