If you know me in real life. No you don't.

Being trans isn't like puberty, it's not a phase. It's not a way of being quirky or trying to be a minority and claim rights. Being trans is a mental state, you cannot tell anyone who has said they are trans and people have told them they can't be trans due to the way they act, dress and speak. Clothing, makeup and personality is not gender reliant and should not be labelled as gender specific. 

Some people cannot afford to change physically, surgery is expensive, some households don't accept it and they are told on a daily basis they should k*ll themselves, not exist and are abused and oppressed because of it. 

Trans people do not deserve the hate and discrimination they get for being who they are and others who may not be trans but are found supporting other people within their community. The way people express who they are as people has nothing to do with you or others.

It is ok to question who you are, what you are. It's ok to not identify as someone who everyone expects you to be. You can question as many times as you want, but you cannot make others feel small, inferior and worse about themselves. A lot of people struggle from low self esteem, depression, inferiority complexes and a lot of other things, you can't make that worse for them by being ignorant.

Before you tell someone they cannot be something, think about what that means to them before you say it.
