1. The M in SAM stands for model.
2. romantic and sexual attraction are different and can overlap but it's possible to have one without the other. No idea how it's transphobic.
3. Why is it only transphobic if non aces do it? Being ace doesn't exclude you from transphobia https://twitter.com/aimhighitlow/status/1302199682974711809

Lol the idea of "usefulness". a human being does not have to be useful to deserve respect. If it's so stupid and non useful to you do not make an ugly thread on it. We don't choose words to describe ourselves so they'll be useful to some group of people we do it for ourselves

For our happiness. For our understanding. And to explain to people how we are instead of being perpetually misunderstood. It's not so that we can suddenly be useful to someone. What do you even mean by useful?

What is a useful person? Do heterosexuals have to be useful to live? To have rights? To love? Who are YOU to make someone question if their identity is USEFUL? It doesn't have to have a use. Your gender, sexuality, being does not have to be useful/productive/efficient.
