"Our public schools suck, therefore all public schools suck, therefore we should stop trying!"
This is not a valid argument.
You read all that and still didn't get the point? That the loony fringe are the anti-intellectuals? That if left alone WOULD kill people?
Your argument against this seems to be that since they were stopped, at least to some extent, and didn't get a chance to kill very many people, they don't count? Do people really have to actually die before they matter to you?
