There is no way to separate dissent from disinformation a priori, other than by making assumptions about the other party's good faith. And so, you can paint anything you disagree with as disinformation if you think poorly enough of them, as you've demonstrated in this post. And it's very easy to think poorly about political opponents in particular.
The end result will be no dissent whatsoever, just two groups calling each other liars at every step.
