Ahhhhhh, you really don't know what a strawman argument is do you? ? Awww, poor chap.
I referred to homogeneous societies here and now: "are" and you immediately revert to "so everything was rainbows and smiles back in the good old days". Classic strawman.
I'll help you out:
A straw man is a common form of argument and is an informal fallacy based on giving the impression of refuting an opponent's argument, while refuting an argument that was not presented by that opponent. One who engages in this fallacy is said to be "attacking a straw man".
