Transphobic people should go to hell

So me and my god sister was just in the front room and I was watching TV she was on her phone. She looked at me and asked me the most dumbest question someone could ask. She asked me "are trans people trans because they want to date the gender they are born with?" ..... What... What. She looked me in my face with the most serious face ever. She was like "If they were born a girl and they like girls they make themselves boys to get with them." Then she said just answer the question so I said "they probably just know they are trans at a young age I don't know if that's right but I defiantly know what u said wasn't right." I think she asked that cuz I was watching Samantha Lux on YouTube and she is a trans woman. So I go to a video of Samantha talking about super straight and she said "ur transphobic if u say trans women aren't real women" and my god sister looks up from her phone and say "they aren't tho" I wanted to smack her ass in the face I just stopped talking to her for the rest of the day after that.
