It really just feels like a defense mechanism. When you can't articulate a reason to vote for democrats without naming Republicans, when both sides have gotten consistently more anti-labor for the last 50 years, especially when they don't lift a finger to combat racist voter suppression.
Something more has to be going on here than everyone not acting how you want them to. Even if that is the case, just scolding them will do nothing to arrest the larger forces that are causing more and more people to give up on the system entirely.
I don't mind if people vote, but I would take 30% of the country forming unions over 100% voting any day of the week. Only one of those is gonna fix things.
