I'd appreciate your comments about the last sentence in the following.
In particular, I would like to know if you consider it a comma-splice,
and, if so, what you would do about it (if anything) in a student's
writing?

With all these people I have at least one thing in common, either hair
or eye color, or even disliking or liking the same people. It doesn't
matter what we have in common, we will always have something to talk
about.

Thanks,
Ed V.
