It can definitely be frustrating, and I see this tendency as a similar projection to what I mentioned about admitting to holding contradictory beliefs by suggesting it's the norm across politics to hold contradictory beliefs. Because the other side is secretly a lying, election stealing, authoritarian, fascist party they have license to be the same to remain competitive. It doesn't matter that there's a lack of evidence for that to be the case since their enemies are so cunning, manipulative, and reasonable sounding. If someone is good at making a reasonable argument opposed to your belief, they are an agent of the enemy there to brainwash you.

In pressing some of these beliefs I've had all kinds of interesting rebuttals. I've learned that all academics studying Climatology throughout the entire world are in on a conspiracy to promote the "climate change" hoax to enrich themselves at the expense of only American conservatives who are the only people on earth to know the truth. When I pointed out the living situation of the average academic, it turns out I'm brainwashed. Someone honestly told me that. After providing a list of resources to support my argument, I've also heard that all publicly available data in general is all falsified to promote leftism. Real information might be found at the library if they ever get the time to find their source and get back to me. You only have to experience the charade so many times before you see in black and white that these beliefs are part of group identity rather than the product of forming an individual opinion. There isn't a debate happening, it's just me trying to include as much objective data in our conversation as I can find while they dismiss everything to protect their fragile worldview. I often change my opinion based on new information, even sometimes from conservatives if the objective data they came across happened to support their worldview in some way. The only times I've managed to get through conservative opinions is when it's a young person realizing how much they've been lied to. I was that young person once.

There are plenty of idiot liberals around because there are parts of the country where you can fall into that belief system without ever having to think about anything. These individuals will become conservative the moment they hear the right rhetoric. There are of course plenty of liberals who understand their own beliefs who I have had good and productive conversations with of course. A conservative who understands their own beliefs is someone you really need to watch your back around because they are the ones inventing and perpetuating conservative delusions for their own benefit.

The "left" does not control enough of the government to make a serious leftward push. All they can currently manage is halting the advance.
