To be trite and cliche: extraordinary claims require extraordinary evidence. Your claims make a superficially plausible story, but if you are going to base your moral decisions on something, basing them on these unsubstantiated claims is circular reasoning.

Why do you personally get to set the rules? Vote for people that support the rules that you believe in, but thinking that you can play cultural imperialist, dictating how people should act and what language they should speak, is frankly egotistical.
