I think his point (which is correct) is it doesn't matter if bacteria develop resistance to triclosan. Triclosan is not used to control bacteria in the medical setting and there is no cross-resistance to antibiotics.

Well, it actually is. The debate about whether using Triclosan-containing soap while caring for patients is appropriate is occurring in the medical field. I saw at least one paper out there discussing it in that context (sorry, no url) but I assumed the soap they're using has a higher concentration of triclosan than what you'd pickup in the grocery store. In retrospect I'm not certain that's true.
When my mother had a bone marrow transplant, the hospital used triclosan to disinfect anyone entering her room. A quick Google search shows this to still be a common approach.
