If you do experience transphobia it should be your decision of what to do following an incident. You should not feel pressured into taking any action that you don’t feel comfortable or safe with.
It’s important to look after your physical and mental health if you are experiencing transphobia. Your safety and well-being is paramount and you should always consider this when responding to any transphobia. Make sure you are safe and try to avoid unnecessary confrontation with perpetrators. However, it’s also important that you talk to someone about your experience and not suffer in isolation.
Even if you don’t want any further action at the moment, it’s important to keep a record in case you want to get help in the future, or the incident escalates.
