In terms of gender transition, I've heard plenty of excuses on why I can't identify with my preferred gender, and I have yet to meet a single reason to rethink my decision. While I agree that young children should abstain from gender-reaffirming surgery until they are of age, I think anyone considering surgery should try living as their preferred gender first, see if they like it, and then later decide to fully transition. For those that present any other arguments related to being against transgender individuals, respectfully, it's none of their business to pry into other's personal lives.
