the way you think about yourself is your business, yes; however, sharing those thoughts & language can imply transphobic beliefs that can easily be applied to others. using that language without explaining why you use it can easily lead others to believe you see others the same as you see yourself.
I remember that comment, and frankly I did see how others might think you see their bodies the same… but them immediately saying “you shouldn’t say that” without even asking for elaboration is so ick. trans people are allowed to use whatever language they want for themselves, and they shouldnt be seen as transphobic when they aren’t even given the chance to explain.
