So, I have written 私が商品おじゃない as meaning 'i am not an object' for a human trafficking poster set, using 商品 to indicate object as a commodity. I am having issues with the article following 私....my first thought was to use が for emphasis, but in recollection I am thinking to use は instead.
Any feedback about this particle issue or any other problems with the phrasing would be very much appreciated.
Thank you very much for your time!
