If you deliberately misgender someone and think it is okay because you don't like them, or because they hurt you, or any other reason:
That. Is. Transphobia.
I don't know why this is hard for people.
That. Is. Transphobia.
If you see this and you are in the person's trusted orbit and you _don't_ call it out or call them in (even privately) that is also transphobia.
Having trans friends or trans people who agree with you does not obviate this in any way, shape, or form.
It is dehumanizing.
