I don't believe "cis" and "trans" have substantive content. I do not believe that a male, with male anatomy from head to toe, is a "woman" simply having stated that he identifies as such. I also do not believe that genital mutilation surgery makes a male any more of a woman or vice versa. I simply do not believe it. The scientific community is divided on whether 'transgender' identity issues are rooted in mental illness or not, and of course the sociological and philosophical worlds are sharply divided between postmodernists and realists, the former believing that things like "man" and "woman" are "social constructs" while the latter tend to believe - in my opinion with far greater evidence - that gender identity and biological sex do not vary randomly but in fact tend to match overwhelmingly, with extremely rare exceptions. There is no 'spectrum'. 

Long story short I do not believe these new "identities" are legitimate. That is my opinion. Will the law FORCE me to say otherwise now?
