I didn't even know I was circumcised at birth until like halfway through highschool and I didn't really care after finding out. And having now seen penises that are uncircumcised, I'm kinda glad I was. From my perspective, it didn't hurt and I didn't even know until 17ish years later. Everything works perfectly normally.

All of that was a buildup to a genuine question of why do you feel so upset by it? I don't mean to be argumentative or dismissive, just want to see the point of view from someone else
