Objective truths DO exist, it's just that they're a bit difficult to find in political discourse. I'm sorry you seem to see me as a "bullshit artist." Ironically, I view myself as exactly the opposite. I know I'm wrong about some things, but I promise not to intentionally lie to anyone here.
I can absolutely appreciate what you're saying and the blame game certainly plays a role in identifying with one party over the other but what I am seeing a lot of these days is "Country over Party". Yes it's the Left screaming it the loudest currently but this isn't blame, the evidence is abundant. The shift is real. Dems are fairly grossed out by their representation but remain progressive. Make America Great Again infers it's not now but once was. The Republican Party is openly and unapologetically asking for the people to regress without debate or obstruction. By definition progress is moving forward.
Can't We All Just Get Along... sadly, the answer is no. It can't be overlooked that many progressives were shocked, rightly or wrongly, to discover so many of the opposition's point of view is so far from their own. I honestly cried when Trump won, not because of him but because I had obviously insulated myself to the degree of hate that would elect this man.
The Parties have worked together better in the past... worse and worse as time marches on but this truly isn't the time to make concessions. Democracy is on the line and the right side though possibly uncomfortable with it are opting for complicity.
To engage in a conversation such as the one you are trying to initiate or instigate the Left will absolutely have to see evidence that the right is standing up for Democracy. I believe the Left can still see the center line but the right has turned its back to it.
