"I want to tell a story involving X" where X is something objectionable is totally valid. "I wanna tell a story set in a Middle Ages Allegory and Monarchies are a trapping of that era." is another perfectly valid reason. No agenda. Just... that's the reason.
The issue comes in when it's "I wanna tell a story about how X thing happens but since X is objectionable I'll instead bend over backwards and sideways to present logic within the narrative itself that makes it okay that I'm telling a story about X" rather than just saying "I recognize X is objectionable, but it's what I wanna tell a story about"
Like having Sue Storm respond to criticisms about her Costume having the number 4 as a Boob Window, thus presenting it as the character's choice rather than authorial or editorial intent.
Or put another way:
You wished to draw a woman so you did.
You wished for her to be nude so you didn't draw clothes.
You wished for her to be beautiful so she is.
You placed a mirror in her hand and said she is Vain.
But you are the one who made her beautiful, nude, and hold the mirror. She is nothing but your desire.
And the more surreal:
Write what you want to write, just don't respond to people's objections with explanations from within the narrative. The answer is "I did it because I wanted XYZ to be a part of the narrative. Here's the way I added it to the narrative in these ways to create a consistent narrative". Never "Because the narrative wanted it"
