> I don't think it makes a person anti-American.
I define "anti-American" as any activity that will negatively impact the future of America and it's citizens *and* the person proposing the action is smart enough to figure that out. Since creationism will serve the purpose of undermining science, and since science is vital to the defence, economy and growth of the US... along with being factually wrong and silly superstitous nonsense, creationism is thus also anti-American.
> Which it's hard to educate someone, when you offend them in every post.
You can't reason someone out of a position they got to via unreasonable means. The knowledge and facts are freely available to every American to know that evolution is a factual and ongoing occurance. The rejection of it is based solely on unreason.
> you don't need to do this to be effective.
Facts and reason, calmly and dispassionately put forward, do not work on those steeped in nonsensical ideology. Try talking a Jihadist out of blowing up a schoolbus full of children or a neo-Nazi out of Holocaust denial.
I have to go with Penn & Teller on this one.
