You don’t have to be out to be trans
You don’t have to be on HRT to be trans
You don’t need to have had surgery to be trans
You don’t have to dress a certain way to be trans
You don’t have to behave a certain way to be trans
You really can just be trans and that’s all that matters
Unfortunately these statements get used by transphobes, in arguing against the things necessary to improve the quality of life of a trans person.
You don't need to dress that way to be trans just do it at home.
I think a really important part to add is that all of these are wonderful if they are what you need for yourself. Don’t let the world force you to deny your own truth simply because these things aren’t required for that truth in the first place.
