Perhaps you're projecting your own bias on those who are not as far to the left as you. It is a typical (and lazy) tactic of those on the left to assign all who are not in lockstep with their thinking to be wacko Nazis or racist sympathizers.
Your casual grouping of readers who don't want to see SJW issues shoved down their throats or have Spencer's political beliefs preached to them in an escapist form of art as people who should be enjoying a Nazi Cap is more a reflection of your prejudiced mindset than anything else. A person can disagree with liberal thought and not be an extreme right-winger who enjoys their favorite characters depicted as Nazis.
It is hard for me to believe that there are many on the left who are still clueless about what happened in the last presidential election. Sure, there were racists and ignorant bigots who voted for Trump, but they were definitely in the minority. A lot of his support came from people who tired of the smugness and arrogance of the left as they constantly ridiculed those as racists who were to the right of their beliefs. Trump is a backlash. I guess I really shouldn't be surprised. Look who they voted for: a conceited, self-important candidate who still refuses to take responsibility for the fact that she lost.
Perhaps it is you who should be enjoying Nazi Cap. I imagine it would only take a small effort on your part to imagine the current Cap not as a Nazi but as a radical left-winger making the rabble bow down to your irrefutable ideology. Sounds fun, doesn't it?
I assume you are reading the story. So you know that HydraCap is not in fact a Nazi, he has no anti-Semitic tendencies, and that all the way back to WWII he was against Hydra allying with the Nazis. What HydraCap is is more of a fascist who is heavily influenced by Ayn Rand. Which brings me back to my question: Why don't the right wingers love the story? In what way is HydraCap not a Right wing fantasy come true? What has HydraCap actually done that FOX News extremists like Hannity or the departed O'Reilly (not to mention the radio talkers) haven't openly called for or openly fantasized about in public?
