I hope the irony of your first two sentences isn't missed.
Nonsense. 99% of the population was not opposed. I'd bet that most Liberals and LGBTQ supported GAS for minors. Just read the opinions on this forum. Read the responses, like yours, to people who said "No, we shouldn't let children decide to cut their genitals off". The response, as you modeled above, was "You don't know anything. This is between the doctors and the families. This surgery is saving lives. We are following the research and you're just transphobic."
Irony.
Not any more, you don't.
You are either dishonest or haven't been reading the broad support for GAS for minors not only on this forum but across the Democratic Party.
