Thank you! I'm a microbiologist and you summed up exactly what I was going to post! No antibacterial soap in my house. Period.
It's the detergent properties of soap that kill the bacteria. Regardless, a small percentage are going to survive. When you add anti-microbials to soap, you are ensuring that the ones that do survive are not only able to survive the detergent but also the antibiotic. Hence, superbugs. It really is survival of the fittest.
When you overuse anti-microbials, you also decimate the bacteria that is supposed to live on your skin. This bacteria is good for you. It can keep the bad bacteria from becoming overpopulated. When you wipe it out, it's like giving over your skin to be a breeding ground to the super strong bad bacteria because those bacteria have less competition for nutrients, etc.
