Yey, another battle for the thought police...
Firstly, I disagree wholeheartedly with paedophilia - I find it repugnant, and those involved in acts against children should be given the strongest sentences available.
However, this is not paedophilia. This is people engaging with each other over the internet in a manner of their choosing. To try and "combat" it, or whatever, is trying to make it illegal to have these thoughts. Which is outrageous.
Back in Roman days if you weren't shagging your mother, brother, son, local castrated boys, etc, you were the one who wasn't in the norm.
Today, we have laws that prevent us from the above, and it is by these laws our sense of "decency" prevails. However, just because it isn't decent to do these things, how does anyone have the right to stop someone thinking them, when after all, they are just thoughts?? They are in essence just out of sync with our time line.
I predominantly play shoot 'em ups and car games on my 'box. Running around killing people, and driving at 100+mph in a city are both illegal, yet to do so in a game or on-line community is perfectly acceptable, as it is fiction.
If these sort of powers are given to authorities, to ban thoughts as they choose, then this is a very sorry state we live in, and a million miles from being a democracy.
Everyone has the right to think what the hell they like, and interact with others about those thoughts. If they then physically act on it, and break a tangible physical law (not some bullshit cyber one they're trying to push), then fair cop, book 'em.
Otherwise, leave them alone and work on some useful laws that prevent the good guy getting screwed over, instead of wasting your time on ludicrous scare story laws that are an irrelevant waste of time and resource.
