In school we never used the Oxford Comma and we studied under the British system. When I took Logic 101 in the University of Toronto, my exceptional professor taught us the Oxford Comma and its use in Logic. I was hooked. It just made perfect logical sense to me. I’ve been using it since and have had no complaints, except for a publication I wrote for which excluded its use in their style guide. Then again, languages aren’t always logical, even if they should.
