I'd like to address how censorship is implemented, in a slightly technical way, and how people avoid it. For example, an authority blocks a website by forcing the ISP to filter out those messages. People get around it by using a proxy server or VPN. But if we discuss that, clever students will see that they can use those tools to get around the school filters (censorship). Or perhaps parental controls (my kids are grown and I don't know what, if anything today's parents might use).
It seems very relevant but perhaps a minefield that I don't want to enter with high school kids. Thoughts?
