I never understood why people get bent out of shape over other people's sexuality, lifestyle, or personality. If it makes them happy and they are not hurting anyone else, what's the problem?
They don't have to conform with your way of life, and you don't have to conform to theirs either.
I like how Filipinos approach it. If you are straight, that is okay. If you are gay, that is okay too. If you are a ladyboy, that is okay too. You are not limited to a particular stereotype or role.
And you don't have to modify your body to conform with other people's expectations. If you are a feminine man, that is okay. A masculine woman, that is okay too. Be yourself.
Just let people be who they are. Live and let live.
