Both of my younger children (and my elder, as far as I know) are incensed about ACTA. Railfan went so far as to email both his parents, his brothers, and his teachers, telling us to Google it immediately, and take action. The Red-Headed Menace is talking to his friends.
God love 'em. I am proud of them for alerting people to this very serious piece of legislation. These are my kids: engaged and passionate.
I am not going to write about ACTA, however. I know from experience with SOPA that there will be many people with more experience and better writing skills than I who will be discussing this at length. I'll post links as I run across them.
