No I'm not really scared of anything related to zombies.
- Am I scared of getting infected with a zombie virus (say by air, water, etc.) and dying from it?
-> No.
Why? There are a ton of biological weapons out there that do indeed spread by air or water. Why should I be more scared to get infected (and dying) from a zombie virus than any other virus that would kill me. I'm dead either way.
- Am I scared of the classic zombie scenario?
-> No.
The premise of most zombie movies (the walking dead included) is that zombies do not have to feed and stay functional for an extended period of time (at least a few years). This premise is complete bullshit and can never be realized due to basic physics and biology (a zombie would essentially be a perpetuum mobile).
- Am I scared of the modern zombie scenario?
-> No.
The modern zombie scenario (for example displayed in 28 days later) works on the premise that zombies are essentially 'rabid' humans that kill and eat other humans yet die when they run out of food. This means those 'zombies' will die after 1-3 months (depending on what metabolism rate you go by).
I have a storage cellar with a steel door and barred windows that is impossible to be broken into without the use of heavy tools. I usually have a supply of water and food down there which (rationed) could keep me alive for at least 6 months so I'm sure that I could wait it out.
As you can see there is no reason to by scared by a zombie apocalypse.
