If you told your mother that you loved nature, and she said 'no you don't,' who is your mother speaking to? The answer is that she was not speaking to you, the kid who loved nature. She was speaking to a fictional version of you that she created in her own head. Similarly, when you refuse to accept an LGBTQ+ person's identity, you are politely refusing to acknowledge their personhood. Love requires embracing a person's reality, not a version of them you projected. You cannot love a person while also requesting their erasure.

The first thing I want to point out is that you are acting as a good example of what calmly deconstructing someone's value looks like. It's silly to say that humans have a responsibility to use their sex organs in a specific way. If humans are just parts of a larger machine designed to produce babies, why are we also developing advanced culture and technology? The rabbits are outdoing us by far on the baby production front, but I'm not signing up to be a rabbit by any means. The second thing is that communication isn't the problem here. The LGBTQ+ person has already communicated their identity clearly if the person receiving this info is not accepting it. The problem is that they are choosing to ignore what has been communicated in favor of their own expectations. Love cannot exist in a relationship where one person explicitly decides that a defining aspect of the other is biologically or ethically incorrect.
