Do you see anyone complaining that there was a trans person in GGGB who had flaws in their character? No, you see them complaining that the one trans person in the game literally sexually assaults the MC. But yes, I suppose a willingness to sexually assault someone does count as a character flaw.
Just like the complaint isn't "there's a black rapper/thug in the game." It's that all the black people are rappers and/or thugs.
To be fair, I don't think Evakiss is racist or transphobic. I think she, like you seem to be saying, is trying to appeal to various kinks and doing so in the way she knows how. And GGGB is a billion miles away from being the worst offender on the racism/transphobia front. I just don't see how you could say that mentioning these issues is invalid.
In GGGB, the ONE trans character can be easily avoided, and even WITH reaching the sexual assault content, can be easily avoided another time. There is no "fallout" for said assault, I don't recall ANYONE making a negative comment ABOUT being a trans person, and it is a character that is obviously there for "kink content" as they can be completely removed through gameplay with no repercussions or addressing them in general. Basically "I'm here for the sex" and little to absolutely NOTHING else. So, not the best example of a trans character in a game. But not even CLOSE to being the WORST version that I've seen in a game either. Even so, the issue OF BEING a trans character is basically dropped like a damn ton of bricks and hardly even mentioned at all.
Now, to be fair.... Can't recall his name, but want to say Tyrone/T-bone, something with a T, I think.... is introduced to us AS a rapper. So he has already established SOME level of awareness as a rapper. It makes sense that the other Black men (Who HE introduces us to) are either "fellow rappers", or if not rappers they are his "friends". And again, given his success at rapping, you could even say that they are his 'entourage' or possibly people who work behind the scenes in the studio such as producing beats, or sound engineer, or even possibly 'ghost-writer'. So, as far as "all the Black people being in rap", there is a ton of more leeway involved to justify them being associated "as rappers" even if they aren't actual rappers.
The gang? Well, yeah. Hate to admit it, but the game appeared to be a case of "All Hispanic characters are gang-members", so not much of a leg to stand on. Think that the intention was to represent a "local community" more than imply "all ... are thugs" concept. But, yeah, like I said... kind of hard to miss that one and haven't got a leg to stand on.
So yeah. Easily avoided trans character is flawed as a character... but nobody seems to be for or against them as a trans. Almost like THAT part of their character is completely IGNORED.
The Black people in GGGB can easily be "justified" as rappers, or in the rap industry in general.
Gang ..... uh, nope, I got nothing in regard to the gang.
No, Eva has never done anything that makes me instantly accuse Eva of being an "ist" or "phobic". Maybe not comfortable enough to go too much into character story/background? Decided to keep some people "clumped together" for ease of setting up a moment (situation), or possibly to expand "random friends" for one better established character. Even THAT issue could easily be justified as career choices. And another group that..... yeah, still got nothing in regard to the gang.
However, I should point out that when I play GGGB, I purposefully AVOID the trans character because I don't like "one use characters", and I AVOID the gang, mostly because I don't really enjoy their overall story. So, when it comes to defending/complaining GGGB, my playthough choices tended to be limited overall.
