We've been non-therapeutically lobbing the ends off knobs for hundreds of years as an act of faith (Judaism) or submission (Islam) - without any consent whatsoever from the child (not even the 'informed consent' that 16 years olds trans-kids can have). This practice is still allowed in Australia.I'm happy for someone to be held accountable for being wrong if that goes both ways.
Now, who is liable if a child is chemically mutilated and then as an adult decides that it shouldn't have happened?
