It obviously hasn't occured to you that NOT giving the helmet could be a fatal thing to do.
On the contrary, I often consider both sides of a discussion and such things do occur to me. You should try it some time, you might be pleasantly surprised. It just might help you look around the blinkers which lead you to ignore the sizing issues whilst rattling on about the condition of the helmet and Accy's personal hygiene. If a helmet is too large or too small, the wearer won't care too much about sharing body fluids or flakes of skin if they do have an accident.
See... I'm actually in favour of helmets. And one of those who you claim to be posting "hatred" about them also wears one. Again, that's the sort of insight which you might gain for yourself without the prejudicial blinkers.
So, as I said, with a bit of thought (which Accy might well have given anyway, without your irrational / emotional intervention), gifting a helmet to someone and checking that it fits and they know how to wear it is considerably better than just handing it over and thinking everything will be wonderful.
there is no need for me to explain the logic of something which I simply have not said.
Are you now suggesting that you didn't write:
Why are you so keen that a kid doesn't have a helmet on his head?
