> Or why let our children take any risk?

My daughter does Brazilian Jiu-Jitsu since a few years already now: her uncle is a black belt. She skateboards too. Those aren't "safe" sports. BTW she already dislocated someone else's arm (nothing serious but the other person wanted to "see if BJJ works": she got her answer).

And yet there are sports I won't let her do, like proximity flying or basejumping for example.

Saying: "All sports have risks, so all sports are equally risky" is a logical fallacy.
