A lot of what you are describing here is why leftism is dysfunctional in the west. Since leftism in the west isn't always a matter of material survival, western leftists use it to hyper-individualize themselves. Essentially they use leftist ideology to try to improve their class/conditions within a capitalist system without attempting to overthrow it. They also attack each other when one person does not see another's personal problems as "the one true leftist perspective."
A key factor is sometimes these criticisms are not coming from someone who is looking for solidarity, but supremacy. This is why people become defensive, because these accusations are not always launched with a cooperative perspective in mind, but a competitive mindset that is a result of western societal framing. Many of the examples cited can also be liberal perspectives quietly excusing capitalism. Basically saying "if it was only 'x' group that was removed from power, or put in charge, the current system would work.
I am already pasty white bald. But my shine is respected.
Or they are fear mongering with the intent to sway opinion that societal collapse is imminent so that we all must be ready to use extreme measures.
"Societal collapse" in their mind is the collapse of their privileged life. "Extreme measures" meaning find ways to quietly genocide a group of people before it becomes an open power struggle.
Honestly most of the time I see a variety of ball cap on a white dude it feels like a tell. Not necessarily always a chud but I feel the ratio is in that direction. I would be curious if there is actually data on this or just a prejudice of mine.
Intense fearful gaze is another one, which is why they also love to wear sunglasses everywhere. The funniest thing chuds do is take selfies of themselves scowling with sunglasses on in their pickup truck.
Every accusation is a confession... sadly. 
Of course he would never understand, hes part of the problem.
Everything is political, not just when your views are challenged.
They sound like posters on r/conservative. Don't tell them that though, it will make them furious. 
Sounds pretty conservative to me. They probably hate that character because they are an obstacle to their own goals, but otherwise they agree with that characters philosophy because they do the same thing regarding real world politics.
I would say a third of those games make sense.
Anything WW2, Shooters, and anything 40K related would be my assumptions. I would also throw in Madden. Top of the chud pile would be Call of Duty.
Oddly enough BioShock still has Ayn Rand fans despite the story. Naturally they can't understand that it is a deconstruction of Ayn Rand. They also say the only reason Rapture failed was because Ryan abandoned his ideals...
HE DID BECAUSE HE FUCKING HAD TO BECAUSE HE WAS LOSING UNDER HIS IDEALS. That is the entire point of that story. It's a self contradicting society.
I can't help but wonder if the presence of a Democrat in the presidency just sort of pacifies liberal, left, and radical mass movements and mobilization.
Ding ding ding. You got it.
A former friend of mine went from being a budding leftist to spinning into liberalism during 2020. He then started punching left the instant Biden was in office. The real reason liberals hate Trump is because he demonstrates that their ideals don't work because he can succeed amongst them, and he fires up left wing thought. They were terrified of Trump winning in 2020 because it would have meant the collapse of mainstream liberalism in the Democratic party, which funnily enough I recall them openly admitting this when it was looking like Sanders was actually the front runner.
That said, Sanders also demonstrates why he isn't a solution. He rolled over to the Democrats and let his movement die. When he was pushed, he caved to capitalism. This is why Stalin said people like this are the moderate wing of fascism because they ultimately don't combat it and will actually facilitate it in some ways. He isn't committed to rooting out capital, but he was openly critical of it, which was enough for the Democrats to demonize and destroy him. But he does represent that attitudes changing is possible, and the Democrats were furious that he was able to stay aloft on small donors as opposed to corporate money to fund his campaign. They have relied on that tool to filter out left-ish candidates and he proved it alone isn't a silver bullet in American electoral politics, they need the media too (which unfortunately they also own).
Americans are very far removed from leftist thought. So much so that Democrats pass as "leftists" if they are "progressives". Bernie's campaigns demonstrated a shift that was slightly outside of the political electoral norms in the United States. The Democrats went nuclear, utilizing the press and doing every they could electorally and institutionally to derail the Sanders campaign (including outright cheating in Iowa). It worked, and to their great delight, nobody noticed because Americans are that propagandized.
These two political parties need eachother. Republicans are the real ruling party of the United States, and the Democrats are the seat warmers that co-opt leftist movements and give themselves all kinds of stupid rules so they are excused from doing anything for working class people.
These parties are Bonnie and Clyde stealing from you, but Bonnie has been more upset lately because Clyde is getting abusive, she still loves him though.
