I'm considering pretending to be transgendered to get my lgbt friends to respond when I wish them happy birthday or something on facebook.
I'm sorry, why do you think that will be a good idea?
Isn't it kind of hilarious to pretend to be a transgendered?
Transgendered people are struggling to fight for acceptance throughout the world. Pretending to be one is not just unethical, but shows that you don't have much knowledge of their struggle. Research what real transgender people are going through to educate yourself.
I don't need to research for that, I can become one easily.
Be yourself, don't pretend to be something else.
