This is true for HFS or HFS+ (although zip, equipped with an internal
Apple extension, *can* exclude). I have an UFS volume to also see
with ls at once whether I have resource forks or not lying around.
From UFS it works to exclude. The --exclude <PATTERN> option *also*
allows to prevent files or directories from getting extracted:
tar jx --exclude __MACOSX --exclude .DS_Store --exclude ._\* -f
<archive> <possible set to extract>

Yes, that's true! I did not test what I finally wrote because I
thought tar would show a behaviour from last millennium (tar xbBpf
numbers names) and make a difference between options and arguments
and so I tried to prepare for use as a shell alias or function. The
correct use would be:
tar jc --exclude __MACOSX --exclude .DS_Store -f <archive> <source(s)>
tar zc --exclude __MACOSX --exclude .DS_Store -f <archive> <source(s)>
