> Neither system is perfect, but the latter captures a wider range of views within society.

In the FPTP system in the US, you end up with two "big tent" parties with broadly opposing views. What makes you suggest that this model does not sufficiently capture the width of views within society?

> Germany is a stable constitutional federal republic with proportional representation and power vested in the Bundestag. No reason why the US can't have the same.

There is a lot to admire about Germany, but that vaunted stable constitutional federal republic just about committed economic suicide via an over-reliance on cheap Russian gas and zealous persecution of domestic nuclear. It now has the weakest prospects among its peer nations. Their governing model isn't a guarantee of good decisions.

It doesn't capture the width of views precisely because of the "big tent" parties. When a political party is united and effective, it functions as a weighted average of its representatives. When it's not, it loses power and makes other parties stronger.

If your opinions are outside the mainstream of any party, you will not have genuine representation in any democratic system, where political parties are allowed to form. Some outlier representative may speak in favor of policies you support, but they would be equally effective as an extra-parliamentary activist.
