Being trans anything (being across/between/outside of social categories or what is considered a social 'norm') can be an extremely difficult and confusing process -- if it's difficult for you to understand this, just think how difficult it must be for that actual human being, that person, dealing with being in the centre of those confusing thoughts and emotions. Then add on top of that personal pressure all the outside pressures, judgements and abuse received from other people -- who are judging rather than offering patience and compassion, if not an attempt at understanding.
No one, who is just being themselves and not hurting anyone else, is unworthy of love, respect, and belonging.
If you don't have anything thoughtful or productive to say, don't -- it's always important to remember that you're dealing with other people who are real, they are not jokes or wastes of space, and treating others as kindly and respectfully as possible is just as important as being the best version of yourself.
Everyone deserves that love, respect, and belonging -- making other people feel small, wrong, or unworthy for their identity will always say much more about you than it will about them.
Just live and let live.
