That is probably the weakest Godwin-ing of a thread I've ever seen. Eliminating an unthinking species for good reasons is no no way morally equivalent to massacring an ethnicity for no particular reason.
I wish I'd turned up before the grandparent comment got downvoted to deletion, in order to point out that what we're discussing here could just as easily, and rather more accurately, be considered the result of "a natural competition, when one species eventually loses and dies out".
