I'm not sure we read the same article. (For example, the things pg says people in the 1830s would be horrified to hear do not include the thing you mention--and of course there were plenty of people in the 1830s who agreed with the viewpoint you mention and said it, loudly, so it was hardly something "you can't say" in that time period.) I don't agree with your vituperative criticisms, but I doubt we'll get anywhere with further discussion.
