How would you talk to a GG stranger? That is the appropriate thing IF you do. Do NOT inform her you've read her. ( & btw, if you were wrong, she might beat you to death with her purse like Ruth Buzzi )
My thoughts exactly! I've met some GGs in my life who, well, look like CDers. Like asking a woman if she's pregnant, no way I'm assuming any fully dressed person is a CDer. If you want to talk, keep it short and neutral.
The crossdressing community is one that needs to stick together and continue to be there for each other for whatever one needs. We are always trying to improve the forum to better serve the crossdresser in all of us.
