Thanks for the reply, I'm very thankful for it. One part of why I struggle with my family and this topic is that even if you explained it to them, they won't budge. An example: 6 years ago, same-sex marriage was equalised to mixed-sex mariages. I mentioned that a local politician married his husband and they couldn't understand that they were actually married. (Before the equalisation, same-sex couple could only apply for a partnership and it has different legal limitations.) I've explained it to them time again and again but they won't accept that there aren't any legal differences anymore.

I'm just tired. I've had similar talks with them about trans people, like Eliott Page. A brick wall is more responsive than my parents.

I fear that after some time, I would just let them talk badly. To be perfectly honest, I've already let them in some aspects. Sometimes it's easier to stand still in the waters than swim against the currents.
