Why would anyone want to be a Nazi of anything, soup, grammar or otherwise? While rules of grammar don't apply as much in poetry, it's still important to point out to those who say they're irritated by incorrect grammar and spelling--or who even call out other people on their use of either--that grammar privilege is a thing.
From missing out on job opportunities to facing unequal testing to simply being judged on others and shunned on social media, people with disabilities, or who code switch, or who speak English as a second or third language, or have other barriers are harmed by this "quirk." It's not a quirk or cute. It's harmful and we need to stop doing it.
I get that it's uncomfortable to acknowledge it. It feels terrible! As an English major, teacher and writer, I am so sad that I engaged in this behavior for decades of my life. I also know that by seeing it and tellig others about it, and refusing to judge people by their grammar and spelling, we can help change things for the better and create a more just society.
