Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
And (sorry, me again) another objection is that 'Hawking radiation' has never actually been observed and might not exist, so that whatever is created might not be destroyed in such a short time frame. Is that true or not?

Hawking radiation is another "semiclassical" result. IMHO Hawking radiation is much more solid than primordial black holes, theoretically speaking.

So to sum up:
There is no theoretical model which predicts sucking the world.
Any black hole going through the earth would as well leave some wholes, even if it would not suck the earth, so even the cosmic ray argument is completely valid. We would have observed the beasts.
