Masculinity is in a bit of a crisis right now. Cis men are trying to (or refusing to) figure out how to excise the toxic elements and make a culture better for them and those around them.
This puts trans men in a weird position. We can cling to the old ways, hurting ourselves and others, and in doing so scrape together enough acceptance to pass, or we can risk being called fakers by living in a healthier way.
Personally, I think we're in a good position to lead by example. We are the self-made men and we can decide to leave out the pieces of masculinity that don't benefit us to make for ourselves and others a model of what being a man can and should look like.
Unfortunately, this does nothing to help the passing problem, and tbh I wouldn't be someone to ask. But imo you shouldn't have to give up things you enjoy just because society says things like "men don't use emojis".
I had a lot of issues with the tell-don't-show worldbuilding in this first episode, but despite that I found the story really engaging and definitely want to see more. I'm sort of a sucker for main character bait-and-switch type shows (which is why i try to go into shows blind) and this pulled it off very well... except when they added the fake main character back in later, boo. Overall, I give the premiere a mixed 3/5, but it has plenty of room to grow.
Also, I find the fluffy-haired barbarian sidekick character's eyes very suspicious and I wonder if Clevatess' plan of "become an advisor to a puppet monarch" has already been executed by a different beast lord.
