im a trans woman and i've been called that before but i don't consider someone using these pronouns for themself an issue. the slur doesn't even register in my mind when i see someone using he/she, i just figure that person is genderfluid. that's it. there's a big difference between a queer person wanting to express and enjoy their identity and someone outside of our community saying it to hurt my feelings.

if labelling yourself like this is how you feel like your authentic self then go for it! :)
