Maybe I do need to change my nick to "Bi Since 13" since people seem to be unable to read the other post I made explaining I use the term "lesbian" because most stupid people don't understand "bi" right away but hear "lesbian" and their homophobia starts rolling right away.

And it is a state of mind. Hence why some like it and some don't.
