It's less political if you keep the politics out of it. They don't have to be spelled out to be there. A background image is usually all it takes. A Gadsden Flag (Don't Tread On Me) or Molon Labe, a Blue Lives Matter flag or cap, an NRA or Support Our Troops or as you did, the MAGA hat. All point to political leanings without a word being uttered. As long as it's not done in ridicule (as you did) and it's not being used to push anything, then it's not political. A background image is just window dressing when it's no attention is called to it.
Good for you to write about people that think the way you think, but there's more than just those types of people in the world and you can't help but interact with them.
You can't imagine a Conservative hero? Why not? They're all over fiction. It doesn't take much, you just take a person that you like everything about and give them a different political opinion from yourself. How is that hard? Unless you mean that you can't find any redeeming qualities in a Conservative person. Which says more about you than them. Here, I'll help you. Green Arrow is an avowed Lefty. He's the most Liberal and Left leaning member of the Justice League and always has been. He is a hero. He gets along with the more Moderate members of the JL and the more Conservative members of the JL. Now, a more Moderate member of the JL; Batman. There's no arguing that Batman is a hero. I'm sure you could create a Bruce Wayne type character. Now for a more Conservative member of the JL; Superman. The most iconic superhero of all is very Conservative but also very Libertarian. As Superman he's Apolitical, he does not endorse any political party or movement, but he's from a small rural town, grew up on a farm, raised cows, pigs, chickens, doesn't trust the government, supports the troops, works with the police and has the types of arms and armament that the NRA and the US military would salivate over... by every stretch of the imagination, he's Conservative, but you say your mind can't invent that. Nobody can claim that Superman/Clark is anything but a great guy no matter how you slice it.
I'm a writer myself, so I understand what you're saying, but nobody truly writes just for themselves unless they don't let anybody else read it. When you pour your heart into a project and spend hours creating characters and interactions and crafting dialogue that means something to you and you publish it for others to enjoy, then you are not doing it for yourself. You're doing it so others can enjoy your work.
It's not bullying to comment and critique a published work. As I was told by an agent, when you publish your work, you have to take the harsh criticism with the praise. You have to have thick skin and just smile and thank the person for their comments and critique. I'm not being harsh or bullying, it was offering a different viewpoint that I thought you may have missed.
But, I will continue to play the game, or I won't depending upon my mood at the time. I was just interested in having the conversation. Good luck with further development and updates and I wish you the best in your endeavors.
