There is a difference between hand sanitizer and antibacterial soaps. As Kev stated, antibacterial soaps are at fault for possibly creating superbugs, but alcohol-based sanitizers have not shown to create resistance. The best bet right now is plain liquid soap and water, but it's difficult to find non-antibacterial soaps anymore. I'm currently using Softsoap (ginger/coconut) that is non-antibacterial and cheap.
