That makes me feel reluctant to submit there in the future truthfully. I'm shocked to hear they would have handled that in that way. As an editor myself, I personally revel in submissions like yours. It's not arduous at all to work with pieces of writers who understand their grammar and syntax. It just makes my job easier. Frustrating is when people submit to the publication and you can't even make it through their title without correcting errors. Happy to add you as a writer of Thought Thinkers if you're at all interested! Feel free to vent all you'd like.
