Yes, some 4WD owners over-estimate the capabilities of their vehicle (or their
ability to drive it) and get stuck. But the same happens with 2WD vehicles,
I've had a near-miss doing 4WD stuff in a 2WD vehicle, I almost drove a Ford
Falcon (for the EU people - that's much like a Ford Mondeo but quite a bit
larger, http://www.ford.com.au will show you pictures) into a river that was
deep enough to destroy the vehicle. (*)

Yes. If you add extra services without adequate consideration then you can
get yourself into trouble. But I don't think this is a valid criticism of SE
Linux. Home users may offer extra services because of having SE Linux, but
they should be in a good position to make an informed choice about whether
their goals exceed their skills. Corporate sys-admins usually don't get a
choice, their boss tells them to provide a service regardless of the risk,
for them SE Linux only has benefits for security.
