Hey Z long time! This is their latest tactic using antibotic resistant bacteria as an evolution. They are so desperate to find proof no matter how manipulated to keep their fraud alive.
I'd counter it with this: if we killed everyone with red-hair for two or three generations wouldn't our population become "red-head resistant"? Moreover, would such an alteration of the content of the gene-pool make us "a different species"?
And yes, we can validly use genocide as an analogy, because that is what our antibotics are doing: killing an entire population based on some trait.
