I wonder how it is possible that people who know how important it is to be properly addressed refuse to address women according to their wishes?
Many women do not want to be addressed "pregnant people" because for hundreds of years their role in society was restricted to being pregrant. This should be obvious.
If You want inclusive language - You can easily say "women and other pregnant people" or "women and trans men" or whatever trans people wish to add for themselves.
I may also point to the fact that when male born people can force whatever label they wish on female born people - this do not serve trans people very well.
