In society we routinely have opinions about things which don't affect us personally. We have opinions about murder, for example, and we made it illegal. None of my family have been murdered before. I'm neither a police officer nor a judge nor criminologist. I'm the least qualified person in the room to have an opinion on this, and yet, democracy gives me that right. I choose to continue to vote to make murder illegal because I think it is immoral.
Likewise, I think it is immoral to do this to children:
In one particularly shocking case, a girl who wanted to become a boy began taking hormone-blocking drugs at just 11-years-old. Almost five years after the treatment began, the puberty-pausing drugs induced osteoporosis and permanently damaged the teen’s vertebrae, severely limiting the teen’s mobility.
“When we asked him regularly how his back felt, he said: ‘I’m in pain all the time’,” she added.
