There are girls starting puberty at 7 and others at 14, very specific time as you say…

No, it means you don’t go through puberty then. Cisgendered kids are given them for condition like precocial puberty, and they go through it just fine when they’re no longer on the blockers.

You’d understand these things if you bothered to examine any of this topic beyond shouting, “TRANS BAD!”

Name that time. Go on. Please.

Call everyone who doesn’t fit your make-believe timeline broken somehow.
