As someone who also didn't like Sena's job as Wuk Lamat, I can tell you that you are really missing that there are 100% for a fact people actually being transphobic, calling her a man, saying all kinds of crazy things that have genuinely nothing to do with her job as a voice actor in Dawntrail. Nobody cares if you criticize her job as Wuk Lamat, but there ARE genuinely people being transphobic towards her, too.
I can link you some right here:

And no, no one is saying those are the majority of criticisms lobbed at her, either. All people are saying is that the transphobic comments do exist and we can see them with our own eyes. You can criticize Sena for her VA job and behavior all you want, but don't be transphobic about it, then people are just hurting random trans people like your 2 trans friends and that sucks, they have nothing to do with Sena or her behavior.
