Why does celebrating or embracing my womanhood now feel like its a threat to other peoples rights?

I may have limited exposure and knowledge of all the aspects of feminism, but as a female born woman who completely embraces her physiology and sexuality as a woman and developing my own personal relationship and identity as a woman I would like to be able to keep that word for myself. I feel protective about it and it feels like if I don’t change what that word means, then I’m excluding people and therefore a bigot or transphobe or someone hateful. Why does celebrating or embracing my womanhood now feel like its a threat to other peoples rights?

I have commented on posts and replied to comments on facebook and twitter.

I am holding my breath because I feel I will be attacked harshly for speaking up.
