When I was about 6/7 there was a talk that made reference to the violence of Teenage Mutant Ninja Turtles. When we got home, all my TMNJ figures were packed up into a plastic bag and put away in the loft. At least they weren't thrown in a wheelie bin.
When I was about 13 there was a local needs (Yes, a WHOLE talk) on the evils of Pokemon, complete with the statement that Pokemon was short for pocket demons (not true) No more Pokemon Blue for me.
I remember explaining to my PE (Gym) teacher, in front of my whole class, that I could not play for the football (soccer!) team as he had asked because they played Saturday morning and I had to go out on Service.
I am sure I remember each and every time I was invited to a school friend's house, or worse, a birthday party. 'No, sorry I can't...'
Sitting in the library whilst the other kids sang Christmas carols.
Having to spend a week studying on my own whilst the rest of my entire class was on a trip to France, because my parents couldn't guarantee that I wouldn't be given blood if something were to happen to me.
What did the bastards rob from your childhood?
