No, you are not a victim. You were not injured or harmed. You might be emotionally distressed, but not to the degree where it's accurate to call you a victim.
And yes, I told SlimReaper to suck it up. The same way you suck it up when your partner breaks up with you. The same way you suck it up when you don't make the basketball team. The same way you suck it up when your dog dies. You might be emotionally distressed but there is nothing you can do about it aside from dealing with it, moving on, and trying again in life.
You had *** with a person and then found out they were a transsexual? Then boo ****ing hoo, princess. Cut ties with that person, deal with it the same way you would the above mentioned scenarios, and continue living your life and try again. That's the only thing you're allowed to do. You don't get to hit them, you don't get to take legal action, so handle it and move on with your life instead of *****ing about it.
I never said it was okay for them to lie about it. I said that a transsexual SHOULD tell the truth, but the timing of when that should be done depends on the couple. There is no universal point where a transsexual SHOULD reveal they are transsexual. YOU would want that to be at the very beginning. That is NOT the same for every person.
