What if that country was Iraq or some other islamic country - would it be wrong to sell people in those countries on ideas that are fundementally opposed to everything their country was founded on or believes in.
It would be futile and frowned upon, but it would not be fundementally wrong.
I am not saying America’s foundation/beliefs are wrong, I am just saying it is wrong to assume they are right and define anything not consistent with them as ‘wrong’.
