Okay, I'll ask again. Exactly how does disabling ICMP redirects on my router prevent traffic from being intercepted?

It stops *one vector* of MITM attack. If a router honors redirects (and it never should), an evil host can intercept traffic of hosts that aren't on the local network. This is 5000% beyond the scope of the original question, btw. --Ricky
