You didn't attack embedded routers, you claimed they were entirely secure.
"Without opening port 80 on your router, and pointing it at your desktop
machine, the risk of getting hacked is, to all intents and purposes,
zero. However, once that port is opened, the risk is, by definition,
infinitely greater."
Do you know what "infinite" means? The only way the risk can be 'by
definition' infinitely greater, is if there is NO risk in the first
place. I.e. the router is 100% secure.

WAKE UP! The above relates to the KERNEL ONLY!

NO! What the hell does that have to do with opening up a port on a
server? That is a client idiocy, and it makes no difference if the
server runs on Linux or XP.

No wonder, you're paranoid.
Tell me, are you one of these people who blindly blocks all ICMP packets
too?

As far as I can tell, you pretend to be some sort of security expert,
yet apparently you know absolutely nothing about authoring network
software, otherwise you would know at least the basics like where your
responsibilitys as an application programmer take over from the kernel.

And once again, no evidence that XP itself, anywhere in the lower level
networking layers, is any more or less secure than Linux.
Note, I hate XP, so I think I am in a fair position to be critical of it
if it deserves the critism.
