Basically, I think that sexual assault in prisons should be taken far more seriously for everyone. That may mean every prisoner should get their own cell regardless of sex or gender. I don't think housing cis-women and intact trans-women in the same cell alleviates this.
The trans men in jail abusing cis women is real thing. They are housed together now. The trans women being raped or abused is incredibly frequent thing - includig by guards. (Male on male rape is a joke, basically. Transwomen in prison are assumed to enjoy sexual abuse basically.)
But despite the former being literally about cis women safety too, it just dont interest people. There are many ways to make prisons safer and making it so trans women or gender non conforming men are a bit safer is topic only for radical trans activists and no one else.
If there is heated discussion about issue that dont currently exist which ignores issues that do cureently exist, it is ok to call it talking point.
