What does any of this have to do with the US?

The United States routinely has states, especially in the South, trying to get rid of evolution from textbooks, that fault line is usually the battleground between religious zealots that desire to inculcate their biblical worldviews into the formal education system.

Of course there are also contests to control history, sex education, politics, etc, because those are far more political.

The periodic table though, hoo boy, that's a new one.

Yes, there are plenty of people in the US who are proudly and aggressively ignorant for ideological reasons, but what does that have to do with a discussion of what's going on India?
