> Calling voters selfish because they didn't vote for your candidate is just pure idiocy.
The GP did not call voters "selfish". It said
> People routinely vote for candidates that will worsen their lives [...]
Now, I would personally reword that as "People routinely vote for candidates despite evidence that these candidates policies will worsen one or more aspects of their lives ...".
But nowhere is there the suggestion that "you didn't vote for my preferred candidate and therefore you are selfish".
And most of those boil down to “voting for X decreases the things I care about increases the things I don’t care about; therefore those who care about those things are voting insane.”
It’s inherently an argument that democracy does not work.
I guess we can see how subtle a skill good messaging is - one can so easily come across as a moralistic busy body if one doesn't listen and connect before trying to persuade.
The suggestion wasn't overt, it was kind of implicity - telling people that they don't know their own self interest, even when they manifestly don't, is not very ahh "politic" :)
