Being trans in the abstract is good and virtuous. Being trans in reality is messy and difficult. It's not that you're only trans when it's convenient, it's that you're only trans when you're the specific trans person they made up in their head who totally agrees with them and also happens to think they should be able to say the n word when they're singing Lil Baby songs in the car on their way to their job as the associate director of client relations at some regional insurance company. You're supposed to say things to them like "yass kween" and "slay" and "you're such a Ravenclaw," not anything politically challenging.
