I truly think that the parents who think that it's OK to take your babies and children to these things in the main are doing it with no malice intended.
I doubt they have any idea of just how many perverts, nonces and just if they could and got the opportunity they would type men (and it's almost always men) exist in this world.
They are probably unaware of the fact that it is possible to sexually assault a child in front of 100 adults and not one of those adults will notice.
It's perfectly possible to sexually assault a child sat on your lap with their mother sat directly in front of you looking straight at you.
These men don't need to take your child off to an isolated spot to sexually abuse them. They can literally do it in front of your eyes.
These men don't have anything else really in common apart from being men. Its not just the dodgy bloke who everyone in the neighbourhood gives a massive swerve when they see him.
These men aren't just some scummy dodgy bloke that smells. they are your bank manager, your doctor, the kids babysitter, your brother, their friends dad.
