Never said they were all children simply that children can compete at the highest level of the sport. You are the one who brought up the "adult sports". Also to your previous comment, size and strength absolutely equals adult. Adults are stronger than heavier than teenagers pretty ismply. There is a reason you dont see teenagers at the highest level of strength and combat sports, certainly not 15-17 year olds.

Sure and the most popular sport by far where you are from is literally played by children at the highest level. Being more popular doesnt make it more of a mans sport.

Do you deny that association football can be played at the highest level by 65kg children? Sure I know what rugby union is, league is superior anyways. And if you wanna talk about pads how about the suit of armor that cricket batters, baseball players literally just where a helmet with no face cover. Some dont even wear batting gloves and they face much higher velocities than cricket batters.

Yes like American football where you cant be a 16 year old 65kg twink and play be at the top of the sport. That actually goes every single one of the big 4 leagues. You are never going to see someone under 18-19 years old and under 70kg in the NHL, NFL, NBA and MLB. American sports require a level of size and strength that teenagers dont have. You literally need to be a full grown adult to play American sports, you dont need to be to play soccer.

Funny thing here in America we play soccer as kids and then grow up and play adult sports.
