Only women have the physical sex organs to become pregnant so only women need access to abortions. Using the term 'women' or female pronouns in relation to abortion access is perfectly normal and not in the least transphobic.
You can only change socially constructed gender. You cannot change your sex.
If a person who has been born a woman wants to identify as a male then that is fine. However, although that person can become pregnant, they only do so because they have female sex organs,. They are therefore a woman, irrespective of whatever they wish to be called or how they see themselves.
Transgender people need to just accept you cannot change sex. Dictating how they should be referred is purely political correctness and doesn't necessarily mean others regard them as such. It may mean we are all polite in doing so but don't ever regard them as anything other than their birth sex.
The term 'Cis women' is ridiculous. The correct term is just 'women'. The young can be indoctrinated into being cool enough to use such terms but, when it comes down to it, there are still only men and women in the world and it will always be determined by the sex organs you are born with.
Transgender people need to accept that non-transgender people are not the ones who need to change the terms used about themselves. If there is a case for anything other than men and women, then it is for transgender people to have a separate sub-term of men and women to describe their sex. It is not for the majority who are non-transgender to change their descriptive terms or sex-indicating pronouns.
