The "all problems will be solved if all my political policies are implemented" seems to be a fairly insidious strain of authoritarianism that is infecting the progressives.
You must have missed the part where they referred to human beings who they disagree with as "a rot in our system". The fact that you're apparently blind to such toxic rhetoric isn't surprising--it is increasingly common among progressives.
It’s not the voting humans who are labeled as the rot, it’s the cycles that result from the exercise of that bloc’s outsized voting power—as said in the second part of your quoted excerpt: “… that way they are voting is causing problems.”
I’m not suggesting the original wording was great and non-toxic, but I don’t think the poster said what you interpreted them as saying.
