Accomodation to receive good medical treatment is more important than accomodating feelings about words.

Those things don’t trade off against each other. What trades off is accommodating some people’s feelings about words vs accommodating other people’s feelings about words. Since these different feelings are about the same words both sets of feelings can’t be accommodated. When we as a society make our choice between two incompatible options we express our values.
