Anything can be made to sound brutal if you just describe it. This is a very common, very annoying, very lazy way to make it seem bad. You take a clean, surgical process done by professionals, and just describe it as "tearing their bodies apart." You can do the same with any other surgery. A heart surgery could be described as "Ripping out their heart and shoving a new one into their torn-open chest." And if the next thing you're going to say is "well a heart surgery is life-saving," SO IS GENDER AFFIRMING CARE.
