I think this is an issue with people being offended by definitions. Slavery did “help” the economy. Was it right? No, but it did. Mexico’s drug problem helps that economy. Adolf Hitler was “effective” as a leader. He created a cultural identity for people that had none and mobilized them to a war. Ethical? Absolutely not. What he did was horrendous and the bit should include a caveat, but we need to be a little more understanding that it’s a computer; it will use the dictionary of the English language.
