Just because they don't use words like dick doesn't mean they aren't using vulgar ad hominems. The mistake is believing that people can distort history but as long as they're being nice about it, it's cool. The US is no more the beneficiary than any other country, so acting like the US is what it is only because of 400 years of loot and plunder (OP's phrasing) is ignoring that the Germans, French, and Russians would have looted and plundered each other and others (and did) for centuries. Therefore, the loot and plunder can't be the sole or even main reason behind American success, which is what the article was talking about.
If an African-American was to wander into a thread with similar sentiments about African-Americans, it'd be recognized for the prejudice it is, and ironically most of the posters here would recognize it there, too.
