This is demonstrably true in many scenarios. Such as, males being transferred to women's prisons because they say they are women. As a consequence, female prisoners have been sexually assaulted and raped by these men. Drawing attention to this isn't misandry, it's reality.
Trying to argue the "facts" with anonymous internet denizens is pretty much useless, because especially in today's post-truth landscape, you can find justification for any horrendous opinion if you dig deep enough. That is even assuming the person you're talking to is even real and not an AI, a bored sociopath on an alt account, a paid shill or otherwise.
Thankfully, spaces like these are very much not representative of real life, where most individuals are nice, decent people minding their own business, and "saving face" isn't seen as such an imperative away from the public scrutiny of the internet.
In the real-life conversations I've had about this issue, most people are horrified when they find out that men, transferred to women's prisons due to trans activist policy, have been sexually assaulting and raping female inmates. Keeping in mind that this isn't a hypothetical about what might happen but is a direct result of harmful policy, and involves documented cases and real victims.
It tends to prompt a rethink about this whole topic.
