Hey now, the reasons people have for steering their kids away from contact sports are valid. They don't need to suck it up.
Yes, kids get hurt in other sports. One of my daughters snapped her wrist in two in gymnastics, while being 'spotted'. I was thankful when she opted for swim team after that.
My dad and brothers played football, baseball, basketball, and hockey. Dad with a leather helmet. The experience was incredibly powerful for him and I have no doubt shaped his life for the better. However, he started having brain bleeds in his 60s which gradually robbed him of all his memories until a major stroke killed him. He was otherwise extremely healthy, no cholesterol or high blood pressure, not on any medications at all. But he had been a football star and I have no doubt that the blows to his head played a part in his brain issues.
My brothers all had injuries and surgeries when they were in high school and now that they are older, those injuries cause them more problems. They can't play tennis or many of the sports they used to play. They can golf, so that's nice.
My sister was a fanatical exercise instructor. Obsessive actually. Now her spine is damaged from all that impact and she cannot even vacuum the floor. I was talking to her yesterday and she said, she just wants to be able to keep her house clean, garden, and go for walks. All things that she could be doing now, had it not been for her choices (as an adult)
The reasons to avoid wear and tear on your body are self evident. The role a parent plays in steering their children is difficult, because they know what can happen. So, saying that they should suck it up is not really a valid answer.
The most you can say is what you would choose for your own children. Implying that others who choose differently than you are not tough enough isn't valid. Toughness has nothing to do with it. When you are making choices for a minor, the responsibility is real.
Heck, I wouldn't let my girls pierce their ears or get tatoos. Not on my watch. Told them if they wanted to do it when they were 18, it was on them.
One more story, I payed $$$ to put all my kids in braces so they'd have straight teeth. Once the braces were off, it was on them to continue wearing the retainer. It's about as hard to get a kid to wear a retainer as it is to get them to practice for music lessons.
Now that they are older, every one of them asks me why I didn't force the issue more.
As a parent, there are always going to be things that your kids hold you responsible for, even if it's not your fault
