yum update error with libselinux

I have selinux=0 in grub.  Am I going to have to enable it every time I
want to run yum update?

Also, trying to 'yum remove libselinux' lists a huge number of
dependecies, basically everything, are they all really dependent on
selinux?  Is there some way to cleanly completely remove selinux from
the system?  Is it possible to have a fedora core system selinux free?

Thanks
