Not going to call them chestbinders, because that hides what they are and what they are doing to women's bodies. They're for flattening and disguising women's breasts.
So many things to question about the trans movement, but why are none of these "woke" people noticing the glaring misogyny in women/female people using painful and harmful contraptions on the female parts of their bodies to modify or reshape them? I'm sure they'd disapprove of "cis" (their word) women getting plastic breast implants to fit a pornified ideal, so why is there this acceptance of erasing or removing breasts?
This article is a case in point. The writer it is planning a double mastectomy which the writer is dreading unsurprisingly because the chest binders are causing injury. They caused shoulder dislocation which the writer is claiming it's because of an autoimmune disorder. The binders were also making the writer's hands go numb.
There's also this:
This is the binder that comes out on days where I’d normally have to force myself to leave the house in a sports bra and a baggy shirt because my whole body hurts. This is a step up from that and it allows me to take breaks from the more intense binding I usually engage with while mitigating the feeling of wanting to give myself to the sea.

Old school feminism, radical feminism was in part about helping women/female people accept and love their bodies. How is this attack on breasts and female bodies progressive? It's no different from Victorian women being laced into corsets to give them 17 inch waists, dislocating their ribs and shifting their internal organs in the process and causing them to faint. I do not get it in the slightest, apart from the fact that patriarchy wants female humans to be in pain the whole time and some of us are only too happy to comply.
