> They all slept perfectly well with fever, so, there's no such thing as a febrile insomniac kid.

Please stop believing your sample of 3 kids is representative of the entire population. You were lucky to have kids who sleep well and that's good for you, but that doesn't make other parents lazy or irresponsible.

> I'm tired of parents who overprotect their children

You know what's even more tiring? Parents who judge other parents while not knowing anything about kids in general just because they happened to be lucky on one particular topic. You won't be lucky all the time though.

> to forcing them to wear helmets

I hope you won't regret saying that ever in your life, but being anti-helmet really is as idiotic as being an antivaxxer.

In my childhood, when the movie BMX Bandits (1983) [0] was super popular, helmets and any kind of protection did not exist. We did all kinds of crazy stunts, influenced by the movie. I don't recall any harmed kid among tens if not hundreds. Scaped knees and elbows - sure, but that's all!
