Yes, it's called proof based on my OWN PERSONAL EXPERIENCE with those on the Left since I have LIFE EXPERIENCES that many keyboard warriors out there lack.
Too many among the Left don't just believe that the Right are wrong; they believe that the Right are EVIL (as Greg Gutfeld and others have pointed out before) which is a mentally unhinged way to look at people with a different point of view as well as with a different choice of candidates, political parties, etc, so the Left are thrown off when they encounter someone on the Right who can agree with points here and there based on facts and irrefutable evidence versus just being diametrically opposed all the time.
For instance, one way I can have a rational conversation with friends on the Left that don't think much of Trump is to agree that not all of his tweets were gold and many undermined his point or a recent success, etc. That is a FACT. That shows I'm not part of a Trump cult even though I greatly admire President Trump who fought for America and I'd easily support him and Republicans versus deranged Democrat politicians (frankly, RACIST and COMMUNIST Democrat politicians these days).
Then, after agreeing about some of his tweets not elevating him, I point out the massive list of his accomplishments that can easily be Googled and I compare how he handled ISIS, Russia, Communist China, etc. to how badly Obama handled things.
Naturally, if one is dealing with a truly unhinged person on the Left (or an Obama cultist) versus a moderate person on the Left who simply votes Democrat, there will never be any common ground to be found because a radical on the Left cannot be reasoned with and won't listen and is too arrogant to ever concede a point, so it pays to just walk away in those cases like walking away from a spoiled child.
