I was simply pointing out that there are two levels to the discussion. Practically, they are interlinked, as you suggest, but it helps to keep in mind that they are logically distinct.
I disagree with you about strategy. The right will have no such qualms about alienating half the country, as long as they can hold on to power by whatever means are necessary. Progressives must be equally ruthless or they will be crushed and, frankly, they will only have themselves to blame.
Like it or not, politics has changed. It's no longer a civilised debate between parties who essentially agree on the ground rules. It's more like a no-holds-barred fight for the soul of America, and we all need to choose a side.
I don't know how much progressive voter apathy contributed to Trump's victory in 2016 but, for what it's worth, I argued for Clinton then, just as I'm arguing for Biden now.
