It is all too easy to laugh it off.
But as parents (as many are on this site) there is the very real possibility that our disenfranchised teen is one of these.
How many posts have we seen on here in the past referring to tween/teen porn misuse, young girls conforming to ridiculous ideals of sexuality coming from porn, the language some young boys use towards their mothers, sisters and other women.
Now, i LOVE gaming. But gaming seems to be one of those hobbies that young boys can be herded into. It's hard to say no if all their friends are doing it and we can kid on that it's a social thing because they can talk to their peers online - but in reality we are isolating them further.
For every kid that is able to have a laugh with their kids on fifa and then go out and hang out with mates there is another that is playing farcry and staying in all night- it is a lonely existence. They might not feel lonely because there's other people on the screen- but by being able to realise their social characters outwith a real life setting it means that they are not bound by normal social norms.
For example, if a group of teen boys are sitting in your local burger joint shouting at the top of their lungs about bitches and ho's or sluts they are likely to be asked to leave. Or they could be spotted by their neighbour who dobs them into their mum etc etc.
Online that is not happening. Their behaviour goes unchecked and is acceptable within this new audience. There is no fear of somebody telling their mum (a very potent motivator when you're a 13 year old boy-whether they like it or not!).
Schools are not set up to cope with this. Curriculum changes do not happen overnight. Teachers cannot be expected to take this on board.
As parents it is our responsibility to know what our children are doing. And if you don't know how the internet works (as many people have proven on Mn over the years by being oblivious to personal data, general terminology or the horror that is some ends of 4chan...) then you shouldn't be letting your kids anywhere near it.
