Well unlike you suggest, I don’t vote blue no matter who, I vote blue because the other choice is demonstrably worse.
You wax eloquent about how things need to change and so you choose to do nothing, but what happens when you recruit enough lefties to your side that the right is able to establish the equivalent of a dictatorship via voter suppression, coups, etc? What then? At that point you are 100% fucked.
Are you one of these idiots who actively want a civil war? Because if so you can give that idea up, it isn’t going to happen.
You are the equivalent of an old man yelling at clouds to change their shape.
You say nothing ever changes, but it already has! Biden, while being not nearly the lefty I would like him to be, has done a fantastic job compared to what I expected. It may or may not occur to you that Biden so far has governed much more left that Obama did.
