Ok, so there is an election system like the one I criticized in the US, just not in every state.

Would you then say, that this is better than “winner takes all” and that “blue wins” is not perfect?

No… because in the example, it was NOT winner take all. Blue one the majority of districts. Red won the other districts. Nobody took all. I feel like you are trying really hard to misunderstand a VERY simple hypothetical example. Yes, winner take all states for electors is bullshit, but that is NOT what is happening in the example, for thr love of god!
