Do we want government mandated censorship, including "underirable" but not illegal sites where they can add them as they wish?
Depends on the government and what is being deemed undesirable as per the wishes of the majority that the elected government are mostly representing. Your question reeks of scare-mongering – is that the best path to be taking ?
Do we want a slower internet?
More scare-mongering (and pandering to individual selfishness) and ignores the fact that technological advances are continually making things faster ... not that faster is necessarily better anyway.
Do we want a filter that makes parents feel comfortable but doesn't protect against chatrooms etc where kids are targetted by predators?
No. Gasp, I said no and offered yet more common agreement ! :)
All we have done here though is shown where ADDITIONAL filtering will be required ... which is still not an argument against ILCF.
If the government puts this in it will never be got rid of.
True ... well, ILCF will mostly fail, but face the fact richary, many parents and most governments are NEVER going to stop trying to take control of the internut now that the "genie is out of the bottle".
The war is being fought on the wrong front here – which doesn't mean that your battle is irrelevant or without merit, but rather just doomed to failure ... on this front.
