I don't think this is such a problem if it is teaching calc-3 and stays on topic. If it's teaching humanities I can see there would be more of an issue.
It will start with the "areas we can all agree on" and then scope creep will occur. This is the safest prediction I feel I've ever made.
Who is "we all"? For instance, the US is 5% of the worlds population. What we call the west is 20% of the global population? Not even to a quarter of it. Most of the population is outside the west. And, within the west there are a number of topics that people don't agree on which are more base.
