So by this logic every toy needs to be tested before it goes to market? Every consumer product evar? Every meal served? Every parent checked for emotional stability and proper Government approved parenting technique? All possibly very fucking dangerous. Where does the paranoia caused by Thomas the Tank engine stop with you people?
There are some bad people in the world. Thats what we have a justice system for. The question is whether you want to preemptively control everything in the universe cause bad shit might happen, or if you want to be free, want others to be free, and when people fuck up, allow them to get what they deserve.
Really you guys dont give a fuck, you are just using THE KIDSSSSSS OMG to search for a hole in libertarian philosophy.
