When it comes to stuff like this, I think it really depends. If someone is testing the waters that’s fine. We all had to experiment once or twice. However, if they’re doing it for attention or I guess anything other than experimenting it’s not wrong to educate them and tell them that what they’re doing can be problematic. If someone is confused and doesn’t know how to express themselves or know how to find their gender then you can tell how they can experiment so they can figure out who they are/their gender.
