I think he/she means men already dating them who won't admit the woman is trans.
I really don't understand this attention whore mentality that people have to announce they're trans to strangers, then expect love and empathy. I also think these people need to be upfront at first contact or meeting about their gender when dating, because leaving out that major detail can result in folks going to jail for assault. None of this getting a number, then going out, and kissing, and after a few weeks, "oh by the way, I was born another gender".
