[Marvel] How does Captain America really feel about the culture of the USA today?

The comics generally portray Cap as an accepting individual, and I accept that. But, the world has really changed. Captain America liking black people is realistic and sensible. But, I cannot imagine how Cap might view gay marriage, trans people, the cold war, etc.

 I know in the comics, Cap saw the Cold War and honestly, his being frozen isn't too extreme because waking up in the 60s after the 40s isn't too bad. But as times age, Cap's time frozen ages too. Take the MCU, Cap has spent almost a century in ice. He missed all of that. What does Cap think of communism and socialism? The CIA? The Civil Rights Movement?

Hell, how does he view Neo Nazis and holocaust deniers? That would be a doozy. Imagine how he feels about inflation too. 

How do you think Cap feels about all this? Is this stuff why he spends all of his time being a hero? Because he knows he's too separated to ever really join back in?

gay people existed in the 1920s, 1930s, and 1940s (have always existed). Cap lived in a major metropolitan area, big enough to have a gay community. Trans individuals existed, even then. 

The communities at the time didn't advertise, weren't open about their sexuality or gener nonconformity to nearly the same extent, but they did exist, they did have culture, and we have photographs, films, songs, books, all about these people from the period leading up to WWII (and all through recorded history, but that's beside the point). 

Cap might be shocked to see a black man reach Colonel in the US armed forces, but only because he wasn't expecting it that soon. Cap might not know how to respond to gender non-conformity, but a person is a person, and that gives him the ability, the empathy, to treat whomever he meets as a human being, worthy of respect, no matter how they present. If it's cinematic cap, his response to most people's differences is most likely, a sincere smile at the thought that this person, whom might have faced persecution in his own time, can find happiness. 

Cap also probably has a soft spot for people who get medical help to be the person they want to be. Remember - steve rogers was a 90lbs weakling before the Super Soldier serum. 

Cap might have a bit of a sputter moment with some people who don't fit the 1940's idea of male or female, authority or subordinate, but in general, cap's portrayal is either savvy enough to figure things out or a good enough person to play things by ear and read the goddamn room till he figures the rules out. Rogers is not an idiot, and he can generally figure out the cultural mores. He would have made an amazing spy if the Super Soldier program hadn't gotten him first. 

As for politics, the cold war, etc... Well, he was raised between the roaring 20's, the depression, and world war 2. He'd probably seen more drastic change in the world than most before he'd been frozen. He might not be surprised that US and Russia ended up at each other's throats. He'd probably been exposed to real Communism/socialism - the progressive, workers-uniting-to-help-each-other kind - and probably does not have the baseline knee-jerk hatred of it that modern americans seem to have. 
He probably disliked the CIA's actions, but from a professional standpoint - they're bad at their jobs based on the publicly available history - and the Civil Rights movement is probably something he both applauded, and wished wasn't STILL fucking necessary. 

I believe we have record of cap Punching lots and lots of Neo-nazis, as well as holocaust deniers. 

Inflation? Ehh. You live through the depression, you get that money changes meaning pretty fast. 

Cap spends his time hero-ing because that's his job. That hasn't changed. It's the same problem superman has - when you're the one that can do the job, you kind of HAVE to do it, because who else will? He may have some issues fitting into modern society, but he does try. And in most continuities, he's had years to do so. You can only bury yourself in the past for so long.
