How can you tell the difference?
One way is that trans-trenders are less likely to get surgery. If you can have a penis and still be a woman, why bother with self-mutilation?
That's when this whole tranny thing exploded. When we were told that a man needn't have surgery, he can simply declare himself a woman and be considered a woman.
Stop calling it “surgery.” Surgery cures or prevents a worst condition. These butchery procedures only maim.
