Subject: Re: FYI
Yeah...it seems simple: Use the john that corresponds with the plumbing you currently have.

However, if you recall, I posted an article where a janitress at a wet market ordered a trans woman to use the men's bathroom and it appears she was corrected. (But it may be she was one of the few who have objections and need to become more familiar and understanding.) So what my friend thinks is so, and actual practice may be two different things. Since trans women can be open there, women get used to them.
