Going through puberty isn't damage or mutilation, it's the process of development through which a child matures to an adult.
As a cis man, I sure am happy nobody forced me to go through a female puberty.
It is impossible for anyone to undergo the puberty of the opposite sex because, obviously, they are not of that sex.
As you are male, there is no method by which you could have gone through female puberty. So your hypothetical of this being forced upon you is nonsense.
One man's "Depression" is another man's "normal brain function; life just gets hard sometimes and that's natural." Explaining to the latter person how dehabilitating the experience is doesn't matter because one person cares about subjective inner experience and the other cares about mechanistic physiology.
Similarly, one person's puberty can be extremely traumatic. People who aren't trans wouldn't understand.
You are male. If you took estrogen - either now, or as a child - you would not begin to menstruate, you would not experience changes to the vaginal surface, you would not start to ovulate, and so on. Female puberty is a developmental process that only applies to those who are female.
I guess it is very hard to refute 4th grade biology.
What would you call it if your parents denied you healthcare as a child, leading to permanent disfigurement? I call it mutilation.
It used to be common to get serious infections at a young age. But today if your parents refused to provide you healthcare (vaccinations, in this case), and you caught polio which lead to osteoporosis preventing you from ever walking normally again; would you also say that wasn't damage or mutilation? I mean, it was the natural process of development through which a child matures, at least until we developed a vaccine.
It used to be there wasn't much we could do for trans people, just like polio. But now we have medications that can prevent the suffering the conditions lead to, and not using them is evil.
