Right or Left Hand?

I know this may really might sound stupid but after several conversations
with a brother-in-law I have a question.....If I am right handed what side
of a bait caster should the crank handle be on and what side of a spincast
reel should the handle be on? I currently have my bait cast set ups with the
crank on the right side of the reel and my spin cast set ups the crank is on
the left side of the reel. My brother-in-law seems to think that I am
fishing my spin cast set ups backwards. Who is right???

Thanks for your time!
Scott
