Meanwhile, there were a lot of people who were intolerant of the restoration of the monarchy and all it entailed. They tended to be the people who went to America on the Mayflower, so they could continue to make the lives of others a misery. Of all the colonies founded, only one in America was based on tolerance. All the others were at least to some degree despotic and governed by bigots.
The "people who went to America on the Mayflower" constituted a very small % of the people who came to what is presently the United States during the colonial era. Many debtors and criminals were transported, and Dutch, Spanish and French colonies were incorporated into pre-revolutionary "America". The freedom-seeking Puritans are part of American legend, but most of the colonies were settled by well-to-do entrepreneurs looking for a chance to make a fortune. Immigrants from all nations, indentured servants, and slaves were recruited as a workforce.
As far as "tolerance" goes, I doubt if the transported criminals and debtors found much, and indentured servants, not to mention slaves, were essential chattel. And the indigenous people were simply eliminated in great numbers.
I find it interesting that you say that Britons that went abroad to every other part of the world they took over by force of arms turned out to be bigoted despots.
Many Americans do indeed consider their own culture and nation as the finest in history and demand an unrealistic degree of respect from "lesser" peoples. The same seems to be true of nearly every other society. Perhaps we can learn from England, adopting the philosophy that "the wogs begin at Calais" and resigning ourselves to the necessity to "take up the white man's burden".
"Many Americans" must be exceptionally ignorant, then. You said it! But a failure to learn from the mistakes of others is a far worse error than making such mistakes in the first place, especially when we have the capability, in the light of present day knowledge, to see those mistakes made in the past for what they are. England has learned from those mistakes and moved on but the USA wants to repeat them all and more besides. You repeat the point about "taking up the white man's burden" but England has never been a particularly racist society. However, I was talking about free speech and hypocrisy!
Yes, many Americans, and Russians, and Englishmen, and people in every other nation on Earth are willfully ignorant and believe in "my country, right or wrong". This condition has existed everywhere through human history.
Thanks for your amusing comment reinforcing my point.
