I also hope you'd be against putting male sex offenders, or other violent males into female prisons just because they identify as trans.
Try again, see if you get it right this time.
I know you don't care about women, what is it you want me to get right?

Let's see, so: "I also hope you'd be against putting male sex offenders, or other violent males into female prisons just because they identify as trans."
Well to begin with, not 'males who identify as trans' in this case as your intent is pretty obvious. So step one:
"Female sex offenders and other violent women in female prisons who happen to be trans."
But step two, why are you specifiying the offense? That's not relevant to what you're saying, unless you're now saying being female and being violent/a sex offender are incompatible, which... no, that's nonsense. It's just there do you can play off the 'trans women are actually secretly violent men out to hurt the innocent cis women!' stereotype in a pretty up-front manipulation tactic. So a question that actually makes sense as a question would be:
"Are you saying female criminals who happen to be trans should be in a female prison?"
And yes. Easily. Because on one hand, even if we take your 'they're just violent sex offenders!' spiel, there are plenty of cis women who're guilty of that and of assault, and guess where they end up? Oh, right, prison. Will they hurt other prisoners? Eh, same odds as other criminals in there, and they're going to be one person somewhere that's filled with guards with equipment and ready-made groups, and if they're actually a violent offender they're going to be in a high security prison, and in turn be surrounded by violent people. There's nothing they can do that any other violent inmate (which, remember, would make up most of their fellow prisoners if that's what they're guilty of) could not also do; even if you want to make it about sexual assault, it doesn't stop being a violation if a cis women perpetrates it. Even in this uber-extreme scenario maybe the one thing that's even conceivably possible is pregnancy, which is going to require you go through the whole 'trans woman,' 'is actually violent rather than, you know, a
normal fucking person,' 'is able to deal with all the prison safeguards specifically designed to stop inmates hurting each other,' 'is able to overpower an inmate who, reminder, is also going to be a violent criminal,' and you're still met with basically non-existent odds because, y'know, hormones kinda get in the way of that even assuming that's a body part they'd want to use because, again, trans.
To take a non-cartoonish depiction of, y'know, real people that actually exist, it's more likely to be someone that made a dumb mistake from poverty, possibly drug-related thanks to the US's ever-successful war on drugs... So. Not someone that's actually going to be a danger, and is way more likely to be a target than a perpetrator because transphobia hardly vanishes in prison. Personally I'd be way more concerned with male guards in a position of power and poor prison oversight and care that allow such problems, rather than plain old transphobic fearmongering that ultimately amounts to nothing. But of course, your intent isn't actually helping anyone.
And of course, what's the alternative? Oh, right, chuck a trans woman in a male prison, and you can fuck right off with that if you're even going to pretend you give a damn about anything even approaching empathy.
