"Unite the country"? Is that some kind of joke? We're in a state of increasingly open civil war, I think it's a bit late for thinking a suitably inoffensive VP pick is going to "unite the country".
Fortunately that sentiment is an outlier from the far left wing. I wouldn't even say it's part of the Democratic left wing. Arguing with you about it is like trying to convince TSwizzle that it's foolish not to wear a mask in order to limit the pandemic.
I agree with you 100%. US political discourse has devolved to:
Left: These people can't be reasoned with.
Right: The left are a bunch of traitorous cunts! Execute them all! Any survivors should be placed into work camps!
So yeah, completely equivalent.
