Who is "We" in this context?

FreeBSD's default for home directories is 755.

And as I have stated before anyone who is taking group rx off
of /root is fooling themselves as that just creates pain for
members of group wheel who now needlessly need to su to
see /root's files.

If you have issues with group wheel being able to read /root
you have far far bigger problems that need addressed than
a simple chmod g-rw /root is going to fix.
