I was talking about a real man walking into a woman's bathroom.  You are talking about something else -- a real woman walking into a woman's bathroom.  I think our points of view are the same --- except that if you dress SO much like a man that you actually appear to be one, then you must expect to be treated as what you hold yourself out to be.  Women have a right to go to the bathroom without construction workers or Van Halen walking in on them.  Any mistake about your sex would have been caused by you.  

Of course, there will be repercussions to this comment:  How dare I use the expression "real man" or "real woman"?  Do you see how crazy this culture has gotten?
